When %CPU is much lower than 100% or much higher than 100% (???), Firefox works fine. If it is close to 100% (usually about 100.2%), it hangs for a while, about 30 to 60 seconds. This happens when I save an image file.

Please go here https://support.mozilla.org/en-US/kb/performance-settings 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.

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

Multiprocessor is disabled.

What do you mean by "recommended size"?

Please look and reread and look at the pic. Enable Multi-processor Support. With the URL provided it shows a drop down with numbers on it. That is multi-processor and you should have that enabled. As to recommended size that is for you to determine as to what works best on your system. Sometimes less is good other times more than the recommended size is good. Test....
