I run firefox alongside chrome. chorme works great. firefox has started to play up on me. Firefox 47. Crashes and stops responding. Get the beachball alot. So I open HW monitor. Firefox using 114.5% of CPU and flash plugin in firefox is using 65% of CPU. I have removed and reinstalled flash but it returns same fault after a day or two. I use chrome for work related and we use google docs, etc. I use firefox for my own stuff, like this forum and personal emails as it synced with my imac at home. I would like to keep firefox over safari if I can as not like safari as much as firefox as this is what I am used to. However if unfix-able I can moved to safari. Any help?
