I have a 3.8GHz quad core processor with 16Gb of memory, I use Windows 7 Pro. Firefox is sometimes taking 100% of my processor to run and it is opening multiple copies with I go in my task manager. I have gone in to Options -> Performance and unchecked Use Multiple performance settings. It is still running slow and using quite a bit of the processor at times. I uninstalled Firefox and put it back on and nothing has changed.

HI, please Copy/Paste about:preferences#privacy into the Address Bar then Enter. Go down to Heading Permissions and at the bottom that heading please make sure there is a Check Mark in the box for Prevent accessibility services from accessing your browser.

Then please go up to General --> Performance and untick everything. change the recommended size lower then see how it runs. Note: 1 = No Multiprocessor = slow again. Try 2 Restart Firefox after making these changes please. Note : Hardware Acceleration is for Video Card, Monitor to see if remain off or to turn back on.
