Hi everybody, I've been using ubuntu for 6 years now, and I've been "fighting" many bugs both on my Laptop and Desktop. I've debugged, reported and helped devs debug quite a few of them.
This time I want to take the passenger seat, cause I'm tired of this (and I'm also very busy writing a thesis).
I can't get my head around the fact that I have a quad core hyperthreading cpu with 9GB of ram and it runs so slow after a few days...
The reasons are probably memory leaks in Firefox and Xorg, and some kind of cpu loop in compiz. Please see attached screenshots.
This is after a boot, having opened firefox with all its 15 tabs, everything is OK:

These are after 7 days of usage without restart. Firefox tabs are not the same, but they are not much different either.
Look at the Memory usage in the first one, and CPU in the 2nd.
Restarting firefox. loading the same tabs:
- Restarting firefox fixes its memory problem but this is not a good solution, and it doesn't solve the other problems.
- Restarting the system "fixes" all the problems but this is not a good solution either!
Any ideas about what causes it would be appreciated!
System is 12.10 64-bit, upgraded from 12.04, fully updated. Firefox is 20.0, Compiz 0.9.8.6.
