I bailed from Firefox for about a year after they added the godawful Firefox button (4.0 maybe?); then I got fed up with Chrome and by that point there was an extension to remove the Firefox button
What’s the Firefox button? I don’t use any extension to remove it, but I also don’t see any button tied to FF itself that I need to remove.
