But that's no longer the case, now that Mozilla has driven away so many Firefox users by making one unwanted change after another. Yes, Firefox was once a significant player. Even UC Browser for Android has more users than Firefox. Even Opera Mini nearly has more users than Firefox has!įirefox has only about one-third the number of users that Chrome for Android has, and even Chrome for Android has fewer users than desktop Chrome.
To put that into perspective, Firefox now has roughly the same number of users in total that individual versions of other browsers (like IE 11 and iOS Safari 9.3) have. It's now only about 6% to 7% of the browser market, across all platforms and all versions of Firefox. The latest web browser market share stats paint a very unfortunate picture for Firefox. Maybe the sites will work, maybe they won't. That means they don't even bother testing their sites with it. I don't know about the companies you listed, but many other web developers no longer consider Firefox to be a relevant browser.
