each time i look into my task manager firefox seems to increase its mem usage slowly. y is that? it would start as ~20,000 K then soon its at 50,000 then 70,000 then 100,000 and the highest its gotten was 300,000. also in task manager under performance the PF usage would increase as well. got up to 1.96GB one time.. ill ive been doing is surfing the web. and as it increases, my comp seems to slo down more. y is FF using soo much memory? is there a way i can stop/prevent this?? could it be my FF extensions? all i have is adblock, fasterfox, flashgot, and the weather thing.
