I switched from Chrome to Firefox after the google login controversy, and have been happy with the transition too.
The only only thing that really annoys me is that when you snap a tab out of a window into a new window, the gesture is similar with snapping a tab into the favorite bar, and I end up with lots of "New Tab" or other unwanted favorites.
Also a small personal annoyance. I got into the habit of always launching the browser by clicking the shift key on the windows task bar icon, so that I always get a new window, irrespective of whether some session is already running or not. But in firefox, when no session is running, launching with the shift key pressed results in the "safe mode" prompt. I wish there was a way to disable that.
