Howdy Testers! At TestMu AI, our users are a big part of our journey, as we constantly work towards giving the best experience to our users. While performing cross browser testing, it is essential to keep up with new browsers launched in the market, so that our users don’t lag in their testing efforts. So by keeping this in mind we’ve added more browsers on our platform, to ensure you have better test coverage. So, hang on to something, as we’ve got a lot to cover!
You can now perform browser compatibility testing on the Chrome latest version, latest Firefox version, latest version of MS Edge and latest version of opera. We’ve added their latest beta and stable version to improve your test coverage. Here are the latest browsers:
Just as a side note, you can perform test on Firefox 20 to ensure your websites works on legacy browsers.
Chrome is one of the most popular browsers in the world right now, with around 63.91% of users opting for it. With such a huge share in the browser market, it goes without saying that you need to test on Chrome browsers. Be it the latest Chrome versions or the legacy ones.

With every new browser version, you’d expect a few changes in how the browser renders certain elements, apart from the performance issues.

Microsoft has been rising up in the browsers wars, ever since they launched their Chromium-based Edge browsers. For testers and developers, it comes as a relief that the new Edge browsers are Chromium based and will follow standard web development norms. Edge browser has been the buzzword recently, gaining traction from various internet users. Consequently, it becomes pivotal to perform browser compatibility test on Edge browsers. Keeping this in mind, we’ve rolled out the latest Edge version, Edge 81, Edge 83, Edge 85 Beta on our platform to help you execute live-interactive test on Chromium Edge browsers.

You can refer to the Edge release notes to learn more about the release.
Refer to Edge Beta release notes to know more about other feature rolled out in the beta release.

Although Opera’s popularity has decreased slightly, it is still one of the top 5 browsers used currently. This is why you should make sure you perform browser compatibility test on Opera browsers, as a significant number of your users might still be using the Opera Browsers. We have added the latest version of Opera, i.e. Opera 68 and Opera 69 beta for real-time testing.

You might be already familiar with the fact that every browser has their own rendering engines and although a few web elements are supported in one browser, it might not be supported in others. In the images down below, I’ve compared the Opera 68 with Chrome 84 and Edge 83.


The usage of translate over time in all document loads in Chrome has increased from 0.5 % in Aug 2022 to 0.20 % in March 2023.
