Mozilla just released its updated Firefox browser for Android adding a ton of new features and optimizations. Most of them come directly from the desktop version of the browser to make the experience more seamless across different platforms.
Firefox and Chrome are updated every few weeks, so it's hard to compare them over time. At one point, Firefox has offered advantages over Chrome in terms of RAM usage, but that claim can go back and forth depending on the revision (and the potential for regressions). Microsoft Edge and Apple's Safari have also made such claims, but in general all browsers are continually improving and beating each other. 2b1af7f3a8
