I ditched Google Chrome for Firefox for a week, and I finally see the appeal

I just switched from Firefox for Android to Fennec, which is the exact same browser bundled by the Mozilla Foundation, with slightly fewer proprietary bits and bops than normal Firefox and available on F-droid. My Mozilla account still syncs and it all works perfectly.

Firefox for Android is still great, but it's nice to see some love for those of us who prefer to stick with open source projects all the way.
