Since updating a few days ago, Firefox suddenly doesn't work properly - it keeps getting very slow, within minutes of launching, and ultimately freezing/crashing. This is new - how do I go back to the previous (non-updated) version?
This has been occurring since the Sept 15 security update. Mozilla seems to be using 100%+ of my CPU.
