Major problems with Firefox include: - full uBlock support - the ability to still be themed - first-party isolation ...Okay, okay, I’m being too cheeky. The common wisdom is that overall Firefox can feel bottlenecked at render and draw times (“less snappy”). That could be a result of a slower JavaScript engine (takes longer to get to drawing), or a result of poorer hardware acceleration (slower drawing), or a less optimized multiprocessing/multithreading model (more resource contention when drawing). I honestly can't see it in the real world, but synthetic benchmark are pretty clear on that front.
