Problem started 3-4 weeks ago. When I start Firefox, its CPU usage is normal and low. After some time, it starts to increase the usage of CPU, reaching 28%-32% of CPU percentage, Firefox become slower and I have to close and restart it. RAM usage is normal.

Note that this happen even if Firefox is open *without* using it. Just after a while Firefox increases its resource needings.

I tried to disable each addons, purged the cache, disable Java, also I tried to reinstall Firefox. Nothing seems to solve this issue.

Windows 7 64bit on i5 sandy bridge 2400GHz, 8 GB RAM.

Is there a plugin-container process running when this happens?

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
