I tried to switch to Firefox, in large part because of the contianers, and I still use it in some places, but the thing that really got me was battery usage. I switched my desktop at work to Firefox, and it was great, and I still use it there, but then I switched by work laptop to Firefox, and (according to powertop and htop) the battery and CPU usage of Firefox was probably 3-4x Chrome. This is a total deal breaker on a laptop.
