Firefox 9 after a while starts using a lot of CPU power, need help!
After a while (2 hours or more) firefox 9 (not the plugin container) starts eating up more and more CPU power, usually just to 25% (because usually i close it and restart it after that), but today i had work to do and i couldn't restart it right then and that resulted in firefix using about 50-60% of a 4 core 3.2GHz CPU (AMD Phenom II X4 955). I'm not doing anything extraordinary just writing emails and just plain normal browsing)
I only notice this because my CPU fan speeds up and makes a lot more noise if using more then 20% CPU power.
I'm pretty sure regular users wouldn't notice anything until it started to slow down their whole PC
I'm using Firefox 9.0.1 running on Win 7 64bit, i have about 20-30 tabs always open (loading) and i haven't tried disabling any add-ons.
I've read on forums that this might have something to do with flash data piling up, or with having to many tabs open.

Hi JoeGP,
Have you looked at the Knowledge Base article Firefox uses too much memory or CPU resources - How to fix or Firefox uses too much memory or CPU resources - How to fix? There is a lot of great information in there.
Hopefully this helps!
It didn't show up when i searched for the problem on Google and it didn't show up when i search here on Firefox's support site either. And the reason it didn't because it's mostly not about my problem.
If' it was one of those things then i would have a high CPU usage the minute i opened my browser, but i don't. It will use a lot of CPU power (after a couple of hours) even if i don't do anything
And yes hardware acceleration is on and so is submit performance data and i use Ad Block Plus, and there isn't a correctly working theme or add-on out there that could use 50-60% of a 3.2GHz quad core CPU
I don't think this is something that can be fixed that easily
