FF 56 which was in beta until today (actually not released until tomorrow) was an improvement. But ver 57 is really nice! Looks great and loads super fast. Finally multi-process is enabled without having to jack with it. So far its looking to be a great browser. I actually made it default! Like the new starting screen look as well. There was a PC mag or CNET article some weeks back talking about ver 57 and the speed was off the charts in their testing against other browsers.
