The new crappy address bar that nobody asked for, pocket, hubs, three different mobile browsers, some useless award and probably more that I don't remember.

Also annoying is how they constantly kill useful features like RSS or bookmark descriptions.

I use Firefox because I still like it better than Chrome and I like to support free software, but it's obvious to me that Mozilla doesn't really care about their users and they're too busy chasing shiny things. I expect they'll keep losing market share until they become irrelevant and disappear.
