after uninstalling firefox
go to start menu search box
type : %appdata%
press enter
in the folder that opens delete the folder named mozilla
then reinstall firefox.

It is possible to remove firefox without removing the add-ons and settings that caused the problem in the first place
They are all located in that folder, not in the registry.
deleting that folder manually will ensure a clean installation.

That's actually not that bad. I've seen mine hit 500,000. That is until I found MemoryFox. Give it a try. Now I consistently run averages around 25,000.

You can enable it for browser only, or for all systems. I usually use browser only because I have enough memory, but I did try all a couple of times. Without it my system would hover around 60% load capacity. With it enabled for all, it drops to around 35% load.

Something is wrong with that entire scenario I currently have 14 tabs open and it's hitting about 190k on ram and between 0 and 11% on cpu usage, and this is a older machine I'm on right now.

At any rate it shouldn't be consuming the entirety of your cpu time. That's an indication of a problem.

Firefox using too much CPU usage...
Within the last couple of weeks, my CPU usage has been jumping from 35% to 60% while Firefox was running. When I closed it, the usage dropped to under 4%. I was running FF v3.6.2 and upgraded to 3.6.10 with no change to CPU usage. I haven't added any more extensions. Any idea why this is happening?
