Top 10 Free Chrome Extensions for SEO: 2026 List

If you do SEO every week, you already know the problem. Most lists of free SEO extensions are either outdated, too broad, or stuffed with tools that overlap so much they create more noise than insight. In 2026, the better approach is not to install twenty browser add-ons. It is to build a lighter stack that helps you check page structure, redirects, keyword signals, broken links, and competitive context without leaving your browser. Google continues to review extensions before publication, monitor them after publication, and provide extra trust warnings for some installations when Enhanced Safe Browsing is enabled, which makes tool selection a practical workflow decision and a security decision at the same time.

At Wordian, we look at browser extensions as support tools, not as strategy. A strong SEO extension can help you inspect headings, verify canonical tags, catch redirect chains, or compare SERP signals quickly. It cannot replace good judgment, a sound content plan, or proper technical work. That is why the best setup is usually a small group of extensions connected to a real process, whether that process starts with an SEO consultation, a deeper technical SEO service, or a structured article writing workflow. Wordian’s own service pages also emphasize that search intent, on-page structure, and technical foundations must work together, not in isolation.

That context matters because many teams still treat browser tools as shortcuts to rankings. They are not. They are a faster way to observe signals that still need interpretation. Google’s SEO documentation continues to frame SEO around crawlability, useful content, and technical health, while Lighthouse remains an official Google tool for auditing performance, quality, and SEO-related issues on web pages. So when we recommend extensions below, we are not recommending “magic ranking tools.” We are recommending utilities that help you inspect the same kinds of elements that already matter in practical SEO work.

Before we get into the list, it helps to set a simple rule. Install only the extensions you will actually use. Every extra add-on adds visual clutter, possible permission risk, and often duplicate data. A content-led team may need a lighter stack focused on page structure, search results, and internal linking. A technical team may need redirect tracing, headers, broken-link checks, and quick audits. That difference is one reason many content plans underperform: the tools are active, but the workflow is not. We have written before about why content fails and why weekly article publishing alone is not enough. The same principle applies here. Tools help when they support a method.

Top 10 best free SEO extensions in 2026

Before looking at the details, here is the full shortlist.

This table reflects the tools’ official positioning and the kinds of tasks they are built to support. It is not a ranking of which brand is “best” in the abstract. It is a ranking of which SEO Chrome extensions are most useful when you want a lean, free toolkit.

What to install first if you do SEO only a few hours per week

If you are a founder, marketer, or in-house writer who does not live inside SEO tools all day, do not begin with all ten. Start with three.

First, install Detailed SEO Extension for page structure, headings, canonicals, and indexing clues. Second, install Redirect Path for redirect and response-code visibility. Third, install Keyword Surfer or Ahrefs SEO Toolbar depending on whether your main focus is keyword planning or page-level review. That combination covers a surprising amount of ground without overwhelming your browser.

If your work is more technical, swap Keyword Surfer out and add SEO Minion or Lighthouse. If your work is more strategic and content-heavy, pair those browser tools with a stronger framework for search intent and article planning. That is where resources like Wordian’s guide to writing articles and blog posts that rank and The Profitable Alphabet become more useful than one more extension icon in your browser.

1) Detailed SEO Extension

Now let’s start with the tool that many SEOs keep installed permanently.

Detailed SEO Extension is one of the cleanest free SEO extensions available right now. Its official page presents it as free forever, with no upsells and no tracking, and highlights page-level insights such as titles, meta descriptions, headings, and X-Robots HTTP header checks. The reason it sits near the top of this list is simple: it gives you the structure of a page fast, without burying you in vanity metrics.

That makes it especially useful for content audits. If you open an article and want to understand its headline structure, canonical setup, indexability clues, image alt coverage, or schema visibility, Detailed gets you there quickly. It is one of the easiest ways to spot problems like duplicated H1 logic, weak meta descriptions, pages blocked from indexation, or strange canonical choices before you open DevTools or a crawler. For teams that publish at scale, that speed matters.

Another reason this extension works well in 2026 is that it stays focused. Some extensions try to become mini platforms inside the browser. Detailed does not. It behaves more like a fast inspection panel for on-page SEO and light technical checks. That is often a better fit for editorial teams, account managers, and consultants who need to evaluate pages in real time during content reviews. When paired with an on-page SEO guide or a structured SEO consultation, it becomes even more useful because the team knows what to look for, not just where to click.

Where Detailed SEO Extension is strongest

Its best use cases are page diagnosis, competitor page review, and pre-publishing QA. If your team writes articles, landing pages, service pages, or category pages, this extension gives immediate visibility into the elements most often missed in CMS workflows. It is also a strong training tool for junior writers because it makes page structure visible in seconds.

Where it is not enough on its own

Detailed does not replace crawling software, rank tracking, or a technical audit. It helps you inspect what is in front of you right now, not the broader state of the site. That distinction matters. A page can look structurally healthy in Detailed and still underperform because the search intent is wrong, the internal linking is weak, or the site has bigger crawl and indexation issues.

2) Ahrefs SEO Toolbar

The next extension earns its place because it combines page inspection with SERP-level usability.

Ahrefs SEO Toolbar is presented by Ahrefs as a free toolbar for on-page SEO reports, SERP analysis, and link opportunity discovery. The Chrome Web Store listing and Ahrefs help documentation both point to free features such as on-page SEO data, SERP overlays, and technical checks including redirects and indexation directives. In practice, that means it sits somewhere between an SEO toolbar and a light browser-based research assistant.

Its biggest advantage is convenience. Instead of switching between a page view and a separate tool, you can inspect page-level SEO elements and also review search-result context more naturally. For content teams, that helps during topic analysis. For consultants, it helps during quick competitor reviews. For technical users, it gives enough immediate page data to decide whether deeper inspection is necessary. It is one of the more balanced SEO Chrome extensions for people who want utility without a heavy learning curve.

Ahrefs is also useful when you are comparing how a page is built versus how it appears in search results. That matters because ranking issues are often not caused by one factor. A page may have a clear H1 and decent title, but weak intent alignment, poor internal context, or thin SERP differentiation. That is one reason content planning should still begin with intent mapping and topic selection, not with extension output alone. Wordian’s own content planning resources lean heavily in that direction, especially in pieces about search intent, content strategy, and why publishing volume by itself does not guarantee movement.

Where Ahrefs SEO Toolbar is strongest

This is a strong choice for page inspections, quick SERP review, and early-stage content evaluation. If you often ask questions like “How is this page structured?” or “What does the live search landscape around this query look like?”, Ahrefs gives a smoother workflow than many simpler add-ons.

Where it may not be your first install

If your main task is purely technical troubleshooting, Redirect Path or Lighthouse may be more immediately useful. If your main task is quick editorial QA, Detailed SEO Extension may feel lighter and faster. Ahrefs is strongest when you want a broader mix of page and search-result context from one toolbar.

A quick note before extension number three

This is also the point where many teams start overloading the browser. They install one page inspector, one audit tool, one keyword overlay, one link checker, one redirect extension, and two more “just in case.” A better rule is this: if two extensions answer the same question, keep the one your team actually uses. That approach reduces clutter and makes training easier, especially for in-house teams trying to standardize how pages are reviewed. Wordian’s training services are built around exactly that kind of operational clarity, because tools become more useful when every team member uses them the same way.

3) SEOquake

SEOquake remains one of the most recognizable names in the browser-extension category. The Chrome Web Store describes it as a free plugin that provides key SEO metrics together with an SEO audit and other tools, while Semrush’s documentation describes features such as organic search data, audit functionality, keyword density reporting, internal and external link analysis, and social metrics. That range is why it still appears on 2026 lists.

Its main appeal is breadth. SEOquake gives you a wider snapshot than some lighter tools. If you want a general-purpose extension that supports fast evaluations across many pages, especially when you are comparing sites, categories, or articles at speed, it still does the job well. It is not the most elegant interface in this category, but it is still one of the more functional ones for quick checks.

The trade-off is that broad tools can tempt teams into collecting more metrics than they can interpret. That is why SEOquake works best when paired with a checklist. Use it to answer specific questions. Is the page indexable? How is the metadata structured? What do the internal and external links look like? Is there an immediate red flag in the audit view? If you try to turn it into a decision-making system on its own, it becomes less helpful.

Where SEOquake is strongest

SEOquake is useful for broader page reviews, quick comparisons, and general browser-based SEO analysis. Agencies and consultants often keep it installed because it covers several common checks in one place without needing a subscription just to get started.

Where it can feel heavy

If all you want is headings, canonicals, and indexation clues, it can feel more crowded than Detailed. If all you want is redirects and headers, Redirect Path is cleaner. SEOquake is better when you want multi-purpose support rather than one narrow function.

4) Redirect Path

For pure technical SEO, few free browser add-ons are as immediately useful as Redirect Path. Its Chrome Web Store listing explains that it flags 301, 302, 404, and 500 status codes as well as client-side redirects like meta and JavaScript redirects, and also surfaces other HTTP headers, server information, and the server IP address. Ayima’s official extension page positions it as a tool trusted for uncovering redirect chains and response issues in real time.

That one capability solves a very common SEO problem. You click a URL, but you do not really know what happened between the clicked link and the final page. Was it a clean 301? A chain? A temporary redirect that should not be temporary? A soft mess involving meta refresh or JavaScript? Redirect Path makes those answers visible instantly. During migrations, canonical clean-up, HTTPS checks, or redirect mapping reviews, that speed is hard to beat.

This extension is also one of the best examples of why not every good SEO tool needs to be broad. Redirect Path does one class of job very well. It does not try to be your content strategy guide, your SERP overlay, and your page-structure inspector at once. For teams dealing with indexing losses, duplicate URL states, redirect loops, or messy legacy architecture, that narrow focus is exactly the value.

Where Redirect Path is strongest

Use it for migration checks, redirect auditing, broken-path investigations, and technical debugging during page launches. It is also excellent for quickly validating what your CMS, plugin stack, or server rules are actually doing in the browser.

Where it is limited

Redirect Path does not help much with keyword planning, content structure, or competitor SERP analysis. It is a specialist tool. Every serious SEO workflow should probably have one or two specialist tools like this, but they still need to be paired with broader inspection or strategy work.

5) SEO Minion

We’ll stop the first half with one of the most practical all-rounders on the list.

SEO Minion is described in the Chrome Web Store as a tool that helps with daily SEO tasks such as on-page analysis, broken-link checking, and SERP preview. Its official page adds features like hreflang checks, redirect checks, SERP statistics, PAA downloads, and search-location simulation. That mix is why it remains one of the strongest free SEO Chrome extensions for people who need broad utility without complexity.

SEO Minion is especially strong for editorial SEO. Writers and content managers often need more than just metadata visibility. They need to preview snippets, inspect link health, review heading structure, and sometimes test how a page looks in a search context before publication. SEO Minion covers that range well, which makes it a good bridge between content and technical work.

It also works well in training environments because its functions map clearly to common SEO habits. Check the page. Review the links. Preview the result. Spot issues early. For in-house teams that are learning to connect writing quality with technical cleanliness, that is valuable. And when that editorial process is combined with stronger planning around topic choice and intent, the output becomes far more useful than publishing articles on schedule alone.

6) Keyword Surfer

If your work leans more toward editorial planning than technical debugging, Keyword Surfer is one of the most practical free SEO extensions to keep installed. Surfer describes it as a Chrome extension for content and keyword research, and its official page says it reveals search data for keywords directly in the search results. The Chrome Web Store listing also says it generates keyword ideas and shows search volumes inside Google results, along with CPC, related terms, visibility metrics, and on-page data. That is why it remains one of the more useful choices for content teams in 2026.

What makes Keyword Surfer useful is not that it replaces a full keyword research platform. It does not. What it does well is reduce friction during ideation. When you search a topic, you can immediately see whether the query is narrow, commercial, informational, or surrounded by adjacent variations worth exploring. For writers, editors, and strategists building briefs, that is often enough to improve topic selection before the work moves into a larger workflow.

It is also a good reminder that not every keyword task requires an expensive stack. Many teams only need a fast way to validate whether a phrase has meaningful search activity, what related terms appear around it, and whether the current SERP suggests a broader or narrower content angle. If that is your main use case, Keyword Surfer earns its place. If your needs go much deeper than that, it becomes a supporting tool rather than the main research environment.

Where Keyword Surfer is strongest

Keyword Surfer is strongest for article ideation, early-stage keyword discovery, and quick SERP-side content research. If your workflow starts from search intent and topic mapping, it is one of the easier ways to keep research inside the browser while you think. That makes it a good companion to search-intent planning and to a more structured article writing process.

Where it is limited

Like most free keyword overlays, Keyword Surfer is not a full substitute for deeper content analysis, cluster planning, or technical site evaluation. It helps you inspect the search surface quickly, but it does not diagnose crawl issues, information architecture problems, or content quality gaps by itself.

7) MozBar

MozBar still has a place in 2026, especially for people who want quick authority-style metrics and link-type visibility while browsing. The Chrome Web Store listing describes MozBar as an all-in-one SEO toolbar and says community users get access to Domain Authority and Page Authority, while also being able to find and highlight keywords on a page and differentiate followed, no-followed, external, and internal links. Those are very specific use cases, and they are the reason the tool still appears in active SEO workflows.

MozBar is particularly useful when your work overlaps with outreach, competitor review, or early qualification of websites. It gives you one more layer of context while you browse, and that can help during prospecting or comparative page review. It is not the most comprehensive free tool on this list, and it does not need to be. Its value is speed: open a page, get immediate visibility into the signals Moz exposes, and move on.

That said, MozBar is one of the easier tools to overread. Authority metrics can be informative, but they are still proxy metrics, not ranking guarantees. If teams treat them as the whole story, they end up making thin decisions about page quality or competitive strength. Used correctly, MozBar is a helpful browser-side signal layer. Used carelessly, it becomes another vanity metric habit.

Where MozBar is strongest

MozBar works best when you want quick comparative context, especially around link types and authority-style signals. If you review potential linking opportunities, compare sites in a niche, or need a quick sense of page-level strength while browsing, it is still useful.

Where it may not be the first tool to install

If your work is mostly content planning, Keyword Surfer is likely more immediately helpful. If your work is technical SEO, Redirect Path or Lighthouse will be more useful on day one. MozBar is best as a complementary tool, not necessarily as the foundation of your browser stack.

8) Similarweb

Similarweb’s browser extension remains one of the better free tools for competitive context because its official documentation says it provides key traffic metrics and performance insights for supported websites. Similarweb’s support content explains that the extension gives a broad overview of traffic and engagement, visits over time, traffic share by region, and marketing-channel distribution. In other words, it helps answer a different question from the other tools on this list: not “How is this page built?” but “What kind of market footprint does this site appear to have?”

That difference matters. Some SEO decisions fail because teams inspect pages without understanding the competitive environment around them. A site may look well structured, but if competitors dominate with stronger brand demand, stronger acquisition channels, and wider traffic visibility, the strategy needs to reflect that reality. Similarweb is useful precisely because it adds market context without forcing you into a full research platform every time.

This makes Similarweb especially useful for consultants, growth marketers, and business owners who want a quick read on whether a site is a real traffic player or simply looks polished on the surface. It is also helpful when you need to compare categories, markets, or brand footprints before investing heavily in content production. That is one reason competitive analysis should come before publishing velocity. We have made a similar point before in articles about why content fails and why publishing weekly articles is not enough.

Where Similarweb is strongest

Use Similarweb for competitor review, category benchmarking, and quick traffic-context checks. It is particularly valuable when you need directional insight about website scale, traffic mix, and overall digital presence.

Where it is limited

Similarweb does not replace page-level SEO inspection. It does not show you headings, canonical tags, schema details, or redirect behavior the way other extensions here do. It complements those tools by helping you see market context, not page mechanics.

A short pause here: tools should match the question

At this stage in the list, the pattern should be clear. Some extensions answer page-level questions. Others answer market-level questions. Others answer technical-delivery questions. The mistake is not choosing the wrong extension. The mistake is expecting one tool to answer every question at once. That is usually the point where teams accumulate add-ons without improving decisions. If the workflow itself is unclear, the better investment is often process design, content operations training, or a targeted consultation session rather than one more browser install.

9) Wappalyzer

Wappalyzer earns its place because technical context matters more often than many editorial teams realize. The Chrome Web Store describes it as a technology profiler that shows what websites are built with, including the CMS, framework, ecommerce platform, JavaScript libraries, analytics, marketing tools, payment processors, CRM, CDN, and many other technologies. The listing also says it uncovers more than a thousand technologies across dozens of categories. That breadth makes it more than a curiosity tool. It is practical.

For SEO, Wappalyzer is useful because platform choices often explain SEO behavior. If a site handles canonicals strangely, injects heavy JavaScript, creates odd URL states, or relies on third-party tools that shape performance, knowing the stack helps you ask better questions. It also helps during technical discovery, migrations, partnership research, and prospecting. A quick look at the stack can tell you whether you are dealing with Shopify, WordPress, a headless setup, a heavy tag environment, or a more custom architecture.

That makes Wappalyzer one of the best support tools for technical SEO conversations. It does not tell you whether the implementation is good. It tells you what kinds of implementation choices are likely shaping what you see. Used that way, it becomes a strong companion to technical SEO work and SEO audits.

Where Wappalyzer is strongest

Wappalyzer is strongest for technical discovery, tech-stack validation, prospecting, and understanding the environment behind a page. It is also excellent when you need a fast explanation for why different sites behave differently in performance, rendering, or plugin-related SEO details.

Where it is limited

Wappalyzer tells you what is present, not whether it is implemented well. It does not replace audits, crawlers, or browser-based page inspectors. Think of it as context, not diagnosis.

10) Lighthouse

The final tool on this list is slightly different from the others. Lighthouse is not just another third-party add-on from the Chrome Web Store. Google’s own documentation describes it as a tool with audits for performance, accessibility, progressive web apps, SEO, and more, and says it can run in Chrome DevTools, from the command line, as a Node module, or through PageSpeed Insights. It earns a place in this 2026 roundup because it is browser-native, free, and still one of the most practical ways to surface technical and quality signals directly inside Chrome.

For SEO work, Lighthouse is valuable because it forces a broader perspective. A page is not only a title tag and an H1. It is also a performance experience, an accessibility experience, a code-quality experience, and an SEO-readiness experience. Google’s documentation explicitly lists separate audit categories for performance, accessibility, best practices, and SEO. That makes Lighthouse especially useful when you want one report that points you toward the next technical discussion rather than giving you a narrow checklist.

It is also one of the best tools for aligning SEO and development teams. Writers and strategists may not care about every implementation detail, but they do care when technical issues slow pages down, hide content, or weaken discoverability. Developers, meanwhile, need something more concrete than “the page feels off.” Lighthouse provides a shared starting point.

Where Lighthouse is strongest

Lighthouse is strongest for browser-based audits, performance review, SEO checks tied to implementation, and cross-team discussions between SEO, UX, and development. Because it can run against public pages or pages behind authentication, it also helps during staging and pre-launch review.

Where it is limited

Lighthouse does not replace a full site crawl, keyword research process, or content strategy. It audits the page you give it. That makes it excellent for page-level diagnosis and weak as a standalone sitewide strategy tool.

Which free SEO extension stack should you actually use?

Now that the full list is on the table, the better question is not “Which one is best?” The better question is “Which combination fits the work we actually do?” Here is a simple way to think about it.

This kind of stack is usually more effective than collecting every popular tool. In practice, the best browser setup is the one your team actually understands and uses consistently. That is also why tooling decisions should follow the workflow, not lead it.

How we selected these free SEO Chrome extensions

To keep this 2026 list practical, we filtered the options using four criteria.

1) The extension still has a current official listing or official product page

A lot of older SEO add-ons are still mentioned in blogs, but some are abandoned, barely maintained, or difficult to verify. Every tool in this list has a current Chrome Web Store listing or a current official product page that still presents the extension as active.

2) It solves a real SEO task quickly

The tools below were chosen because they help with actual day-to-day work: on-page checks, redirects, broken links, SERP review, keyword clues, traffic context, or technology detection. If an extension looked impressive but mainly duplicated data already available elsewhere without saving meaningful time, it did not make the cut. This is also why some famous browser tools appear lower on the list than you might expect.

3) The free version is genuinely useful

Some browser tools technically have a free tier, but the no-cost version is so restricted that it adds little value. Others give enough insight for routine SEO review even without a subscription. This article focuses on those tools that still have a meaningful free use case in 2026.

4) The tools do not all do the same job

A good extension stack should be mixed. One for page structure, one for redirect and header issues, one for quick keyword context, one for competitor visibility, one for link checks, and maybe one for technology profiling. That gives you range without turning Chrome into a crowded dashboard.

Which extension is the best overall in 2026?

If we judge by usefulness across the widest number of daily SEO tasks, Detailed SEO Extension still has the strongest claim to the number-one spot because it is free, light, and centered on practical page inspection. If we judge by content ideation, Keyword Surfer is one of the most useful. If we judge by technical troubleshooting, Redirect Path and Lighthouse are stronger. If we judge by competitive context, Similarweb is the better choice. That is why a single winner is less useful than the right combination.

There is also a broader lesson here. Browser extensions are helpful because they shorten the distance between a question and an observation. They do not shorten the distance between an observation and a good decision nearly as much as people assume. That second step still depends on search intent, editorial judgment, technical understanding, and a process that connects them. Articles like Why do 90% of content pieces fail to produce real results? and Why companies need SEO consultation before a content plan matter more than one extra tool because they address the decision layer, not just the inspection layer.

Need an SEO workflow, not just more extensions?

If your team already has enough tools but still struggles to choose topics, structure pages, or connect SEO work with business outcomes, the problem is rarely a missing browser extension. It is usually a missing process. That is where a content and SEO consultation, training for in-house teams, or a more focused technical SEO review becomes more useful than another free install.

FAQ

What is the best free SEO Chrome extension for beginners?

For most beginners, the best place to start is a lightweight combination rather than a single “perfect” tool. Detailed SEO Extension is a strong first choice because it makes page structure easy to inspect without overwhelming you. If you also want keyword context, pair it with Keyword Surfer. That gives you a practical starting setup for page checks and topic research without turning the browser into a crowded dashboard.

Are free SEO extensions enough for real SEO work?

Free SEO extensions are enough for many daily inspection tasks, especially on-page review, redirect checks, snippet previews, broken-link checks, and quick keyword research. They are not enough for every level of SEO work. Once you need sitewide crawling, structured reporting, deeper clustering, or more advanced competitive analysis, browser tools become support tools rather than complete systems.

Which free SEO extension is best for keyword research in Google results?

If your goal is keyword research directly inside Google, Keyword Surfer is one of the strongest free options in 2026. Its official materials say it shows search volumes, keyword ideas, CPC, related terms, and other data directly in Google results. That makes it especially useful for writers, strategists, and marketers building article ideas or refining search-intent angles quickly.

Which extension should I use to check redirects and status codes?

For redirects, Redirect Path is still one of the most practical free tools. Its official listing says it flags common HTTP status codes such as 301, 302, 404, and 500, and also detects client-side redirects. That makes it useful for migration work, canonical clean-up, redirect validation, and troubleshooting unexpected URL behavior.

Is Lighthouse still useful for SEO in 2026?

Yes, Lighthouse is still useful because Google’s documentation continues to position it as a tool for auditing SEO, performance, accessibility, and more. It is especially valuable when SEO work overlaps with development and UX, since it helps surface page-level issues that affect discoverability and usability, not just metadata. It should be treated as a page audit tool, not as a complete SEO strategy platform.

What is the best free SEO extension for content writers?

For content writers, the strongest free combination is usually Detailed SEO Extension, Keyword Surfer, and SEO Minion. Together, they help you inspect headings and metadata, review keyword context in the SERP, preview how results may appear, and catch link issues before publishing. That is a strong editorial setup without needing a heavy SEO stack.

Can browser extensions replace a full SEO audit?

No. Browser extensions are excellent for fast checks on the page you are currently viewing, but they do not replace a full SEO audit. A real audit usually requires sitewide crawling, indexation analysis, template review, internal-link evaluation, performance checks, and often collaboration between SEO, content, and development. Extensions help you notice problems faster, but they do not complete the whole investigation.

Which free SEO extension is best for competitor analysis?

If your goal is competitor analysis, Similarweb is one of the most useful free options because its documentation says the extension provides traffic metrics, engagement insights, geographic traffic share, and marketing-channel distribution for supported sites. That gives you directional context about site footprint and market position that page-inspection tools do not provide.

Is MozBar still worth using in 2026?

MozBar can still be worth using if you value quick access to Domain Authority, Page Authority, keyword highlighting, and link-type visibility while browsing. It is most useful when you are comparing sites, reviewing opportunities, or doing quick research. It is less essential if your work is mostly technical troubleshooting or content ideation, where other tools on this list may be stronger.

What is the safest way to choose Chrome extensions for SEO?

The safest approach is to install only tools with current official listings or official product pages, review permissions carefully, and avoid keeping large numbers of unused extensions active. Google has also published guidance around extension safety and additional warnings for some installs, which makes it wise to keep a lean stack and choose tools from known publishers. That is better for workflow clarity and for browser hygiene.
