Firefox almost unsuable after latest update for me - lemm.ee

Hey there, I’m a long time firefox user and have never ever had any problems with firefox. But after the latest update, the browser will now just randomly freeze and it happens very often. It will freeze for over a minute at the time, making it impossible to use the browser. I’ve refreshed firefox as suggested on their websites, I’ve reinstalled but still all the same. Anyone got any suggestions to what I can try? Or anyone else experienced the same thing?
