Lately Firefox is maxing out my CPU usage even when I start it in safe mode or install a new user profile. In safemode it is usually closer to 70-80% CPU usage but without safemode it is between 90 and 100%. I have also tried completely uninstall and reinstalling the program but yet the problem still persists. If I attempt to load Firefox not in safe mode then Firefox will crash and stop working all together. At least in safe mode I can still browse slowly but then I don't get add block.

HI, Please : go to the Firefox 3 Bar Menu --> Options --> Privacy & Security panel and under Permissions check (put a tick in the box) the setting to Prevent Accessibility Services from accessing your browser.

Go to the 3 Bar Menu then Options --> General --> Performance and untick everything. change the recommended size lower then see how it runs. Note: 1 = No Multiprocessor = slow again. Try 2, try more until find sweet spot. 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.

Please let us know if this solved your issue or if need further assistance.
