high cpu usage

FFus3r besvarat
Redenegue

I have had it! High CPU usage keeps coming back to kill my computer. 100% after the last update and memory hogged! No tabs running, all add ons turned off. I have used firefox so long, I do not remember when I started, but today, I am moving on. My computer crashed twice from overheating. You have known for a long time that FF has cpu and memory problems, yet you keep releasing updates that hog resources. You do not check your releases prior to releasing them? I hate to go, but you stepped on my toes too many times. Bye!
