StatCounter reports that 64.53% of users worldwide use Chrome as their primary browser. It’s not only the convenience of services and download speed that makes it so popular but also the fact that Chrome is one of the few browsers equipped with various extensions.
Chrome’s still dominating the browser game in 2025. StatCounter shows nearly two-thirds of users stick with it as their go-to choice.
If you’re building QA Chrome extensions, you’re targeting the right audience. Start by checking Chrome’s developer tools to see which testing gaps your extension could fill. Most teams overlook basic accessibility testing within their workflow, so there’s your opening.
You’ll know you’re onto something when early adopters start requesting features you hadn’t even considered yet. It’s not only the convenience of services and download speed that makes it so popular but also the fact that Chrome is one of the few browsers equipped with various extensions.
Less switching between tabs, while you work, is a great advantage for developers and testers, which ultimately saves time.
Here are some key statistics from Pega’s research on how switching tabs significantly affects the average IT team’s productivity:
1
People switch apps on average over 1,100 times a day
2
Employees who constantly switch between apps, 30 times or more, usually have an error rate of 28% higher than those who only use a few apps
3
The average person performs 134 copy and paste actions each day
The last point highlights that employees are often forced to switch between apps using the same data they used to complete a task, especially QA testers who have the same daily steps to check if everything works well. Taking this situation into account, extensions can help immensely and remove this unnecessary “copy-paste” from your quality assurance.
We interviewed some testers and checked all popular quality assurance forums to see which Chrome extension(s) for quality assurance testing they use to make their work more efficient and speed up test executions. Here we go.
Recommended Chrome Extensions for 2025
The QA Chrome extension scene keeps changing, and 2025 brings some solid new players worth checking out:
GoFullPage: Grabs full-page screenshots in one click, perfect when you need to document those tricky layout issues or weird visual bugs that only show up in certain contexts.
BugMagnet: Throws problematic test data straight into form fields without the hassle of typing. Start with the ‘Names’ category — it’ll surface edge cases you probably hadn’t considered.
axe DevTools: Runs accessibility audits right in your browser and gives you specific fixes aligned with WCAG 2.1. Companies using this report find nearly twice as many accessibility issues compared to manual testing alone.
EditThisCookie: Lets you mess with cookies on the fly for session testing. Pro tip: bookmark a few test cookie states to quickly switch between user scenarios.
Postman Interceptor: Captures and tweaks API requests directly from the browser — no need to recreate calls in a separate tool.
Combining these newer tools with established extensions like Selector Gadget and Web Developer is catching regression bugs faster than those sticking to traditional approaches. Your best bet? Pick two that solve your biggest current pain points and get comfortable with them first. (source: QA Madness, research 2025)

Best Practices and Tips for Using Chrome Extensions in QA
Here’s how you can maximise your QA workflow with Chrome extensions — without shooting yourself in the foot:
Stick to what you actually use. Loading up 20+ extensions sounds tempting, but you’ll end up with conflicts and a sluggish browser. Keep it lean — around 5-7 core tools typically hits the sweet spot.
Check those permissions before clicking ‘install.’ Then keep everything updated. Outdated extensions can introduce weird bugs that’ll have you chasing ghosts for hours.
Get your team on the same page with a standard extension kit. When everyone’s using different tools, good luck comparing notes or sharing bug reports that make sense.
Test with extensions off too — spin up an Incognito window or create a separate Chrome profile. You’d be surprised how often an extension masks a real issue that users will definitely hit.
Look for extensions that play nicely with your existing bug tracker or test management setup. The time you save on manual data entry nearly doubles your actual testing time.
One thing many teams miss: extensions can actually help you catch responsive design issues faster than traditional methods. The viewport switchers show breakpoint problems that manual resizing often glosses over.
Stick to these guidelines and your testing environment stays clean, consistent, and actually speeds up your work. (source: research 2025)
