Chrome was the 1st browser we supported, and we have supported it continuously since. This browser has the lion's share of use. It is hard to tell exactly how much since many other browsers 'appear' to be Chrome, making Chrome seem to have a bigger share than it does - but even with that factored, almost everyone agrees it has well over 50% of the market.
We have also since the beginning supported the then current Microsoft browser, currently the Edge browser. It's developers have helped a lot to improve the Chromium family of browers, improved memory management in particular. It may not have a big overall share, but among some corporate buyers it is the mandatory browser.
We support the Norway built browser "Vivaldi", providing another option depending on your preferences. It's use bolsters Chrome's numbers, so it is hard to tell what it's share is, but it isn't a lot. While it isn't a lot - it provides a Nationality option that some of our customers in 2025 are looking for and it works in all our testing, so we have it in our ongoing testing suites.
We have also been able to support the Brave browser for most of it's existence. Again, it bolsters the Chrome percentages, and appears anecdotally to be a much higher percentage of use than the charts suggests, and we know that some of our customers are avid users of Brave and it continues to be in our test suite, though it did have 2 separate years where we had to remove it due to problems they caused by their design mandate, so if you aren't coming from the perspective of loving Brave, you should stick with one of the above three. But if you love Brave, we have good results with it most of the time and continue to have it in our testing suites.
Noticeably missing are the FireFox family of browsers. When Eich was forced out of the company (and many from the team left with him) we noticed a quick decline in quality of FireFox in features that we relied on, and a lack of new features that the Chromium browsers were introducing that helped us improve our offering. As a result we had to stop supporting it. We have tried about once a year, but it remains as a product we are unable to support. At the time that it broke to the point of being unusable, around 2015 it had dropped from having about 30% of the market to having about 11% of the market. In 2025 it was down to less than 3% and appears to still be slowly falling. 2.5% is still a fair amount - one in 50 people, and we will continue to test it about once a year if it continues to be viable, and we'll update this page if we are able to again support it. Unlike Edge, Brave and Vivaldi, using FireFox doesn't boost Chrome's numbers, so it is unlikely to have a higher use than the statistics show.
