I've had all three which is where I got my screen name. I prefer android.
Chrome is working for me, and it interfaces better with all my Google crap. Firefox did work for me too but I removed it to save space for cat memes.Still haven't seen anyone try Firefox for Android and post results.
It's one of thoes permanent apps that can't (or at least I don't know how to) be uninstalled.Have you tried uninstalling the browser and then reinstalling, to see if that fixes the glitch?
