My laptop not used to be being used at maximum, it used beeing used at 50% at max. Sometime used 100% for a few hours if I rendered a picture using blender. I used to not updating my OS since it sometime making the configuration weird, and I have no time to reconfigure it, after I reinstall the new AVG the autoupdate is on it is updated. Now, my laptop using full power everytime I used Firefox, but it did not getting faster, I bet some plugin is wasted out the resource. And the bad thing is, I cannot fix it. Not, every 15 minutes if it on 100% CPU usage, my laptop shutdowned. Anyone know how to limiting firefox CPU usage? It did not happen if I use Google Browsers one. All of my password was stored on firefox database, if I use google I need to retype everything. Im too lazy to do that. :toothy
i dunno - i think i would go back to an older version of firefox
but, i'd also get rid of AVG and turn off all automatic updates :P
Firefox is notoriously bad for leaking resources, this is compounded by certain web sites and scripts/flash. FF 6 and 7 seem to be a bit more stable.
As for laptops, they mostly default to low speed/power modes, you should be able to play with the power settings in Control Panel. Some of the cheaper laptops also utilize desktop class processors, and don't modulate/throttle speed properly. I'd check you have the most current BIOS, and that the BIOS has enabled the features you want.
use google :P
there seems to be a lot of info on the subject

AV is a sham. Huerisitics may find part of a virus but reboot and it's back.
Signature updates don't work at all. Hex one byte and it's invisible to most AV software.
I had a similar problem, so I went back to Firefox ver 3.6.23
In regards to CPU hogs try using process Explorer: http://technet.microsoft.com/en-gb/sysinternals/bb896653
View-> Set Colums -> Process Performance -> CPU History
It allows you to quickly see who is hogging the CPU.
Hope this helps
Im fixed it, facebook plugin is the suspect, with newer flash. It did not compatible with Firefox 8.0. After firefox forcing autoudate without I even know it, they installed an antivirus kapersky, and automatically scan for virus. They found some virus, and it is a cracked software where I dont know how it could be there, maybe somebody used my laptop downloading it. Now everything is fixed, my system back to normal again.
