Yes, Firefox exists. I use Firefox. They try and portray themselves as the scrappy underdog, but really, they are a fallen empire. They were dominant. Now they're not. Yes, Google has done shady things that hurt Firefox, but Firefox has made a number of user hostile moves. Feedback is often ignored because the developers know better. They've started secretly experimenting on their users or sneaking in ads.
They cry foul play but their actions aren't the actions of a freedom fighter.
