On my win task mgr I usally use 25- 26 memory ussage but lately its been running at 70 - 156 thousand. Also my virtual mem goes up to, is there any way to find out whats causing this? I'm running ff 220.127.116.11, when I downloaded 2 it was slow. Firefox is whats using all the memory stuff.
I dont think your problem is firefox.I will give you my task master reading with firefox and the desktop.
Desktop only Cpu usage 1 to 2% Pagefile memory 197MB Physical available 1711224K
Firefox Cpu " 1 to 4% Pagefile memory 209MB Physical available 1690728K
How often do you defrag your PC I have also found it is worth removing firefox and all it folders using start and search.My pc uses F8 to go to safe Mode but midway down the list click to start in the last good configeration This will clear any little blip.
Good Luck and Merry Christmas
