Mozilla Firefox might be a beloved desktop browser, but on Android, its market share looks like nothing but a rounding error. That might be one of many reasons why Mozilla decided to rewrite its mobile browser from scratch with a new rendering engine, a revamped interface, better performance, and more privacy features. Now that Mozilla has had more than half a year to fine-tune the product, I decided to give this new Firefox a thorough test on my Android phone to see how it compares against the standard most people stick with, Google Chrome. Interface and user experience Firefox lets you choose between a bottom-based and a top-based interface. Depending on which you go with, you’ll find the address bar, tab switcher, and menu button on the bottom or the top of your screen. Like on Chrome, you can switch between tabs by swiping left and right over the address bar or instead of using the dedicated button.
