Ok, on Windows 7 64 bit, I basically use Firefox to browse the web, with a DSL broadband connection.
Sometimes while surfing, I see the computer slows to a crawl for a few minutes and then goes all right again. At this time the Task Manager shows 98% memory usage with 3.9 GB being used out of 4 GB ram.

Today when this happened, I ended the Firefox process, and the usage instantly reverted back to normal 600 MB.
So whats happening?

This is the paste of the firefox memory dump: @magicandre1981


Update: The problem may not be Firefox. Here is a picture of what is happening:

  • Have you tried disabling add-ons? Please mention which version of firefox you are using, and also the add-ons. – VenkatH Dec 24 '12 at 19:09
  • @VenkatH Firefox 17.0.1 Addons: Adblock, Abduction, AVG plugin, Nitro PDF plugin, Shockwave plugin – Spandan Chatterjee Dec 24 '12 at 19:18
  • Remove AVG, install MSE and see if that fixes it. – Karan Dec 24 '12 at 20:57
