Firefox is frustratingly slow for me. I can't use it, have to stick to Chrome. Chrome which, by the way, crashes after 5 minutes of using video Hangouts and brings my 16 gigabytes ram PC to a halt when I open too many youtube tabs.
But firefox scrolling is especially slow. irccloud.com is the main culprit (and I use irccloud a lot). It's pretty bad in gmail as well.
The react app my team is working on is also far slower in Firefox. Try scrolling this in Firefox and Chrome and see the difference (the scrubber is at the bottom of the blue area, like a video). Butter smooth in Chrome, horribly slow in Firefox: https://hsreplay.net/replay/7VAKLeMNaXvshAawnUUoni
