    Totally worked! I’ve been having problems with viruses lately and been looking stuff up on the processlibrary and noticed that my firefox.exe process has been running higher than usual [68 thou. K].
    My DSL modem’s light for internet and ethernet were blinking [indicating that I were using them] even though I wasn’t loading websites or anything. So I thought something was using the internet other than myself.
    But anyways… Now my firefox.exe has lowered down just below 30 thou. K and I’m less suspicious. Thanks!

    Unfortunately, this no longer works with Firefox 3.
    Anyone find any tweak for Firefox 3?

  29. starting over Says:

    Hey thanks, my firefox.exe mem usage dropped from 90000k to 45000k but now its climbing back up to 65000k…
    I dont know why mine is so high. I only have a single window open.. Would you recommend anything? Do you think I have a virus? I am using firefox version 3.0.4
