This has been going on for the last week. Box tells me I am low on memory even if I only have one tab of Firefox open( Home page) and nothing else. CPU running at 1% or 0%. Latest version on 12 month old laptop. Help! Task manager details show only two programs using much - Firefox at 172,528k and MsMpEng.exe using 36,404k I am not a computer buff, so be gentle with me!

Other things that need your attention:

Note that your System Details List shows multiple Flash plugins.

  1. Shockwave Flash 12.0 r0
  2. Shockwave Flash 11.8 r800
  3. Shockwave Flash 11.6 r602

You can find the installation path of all plugins on the about:plugins page.

You can check the Flash player installation folder for multiple Flash player plugins and remove all (older) version(s) of the plugin (NPSWF32) and (re)install the latest Flash player.

  • (32 bit Windows) C:\Windows\System32\Macromed\Flash\
  • (64 bit Windows) C:\Windows\SysWOW64\Macromed\Flash\

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem

There might be extensions and plugins installed by default in a new profile, so check "Firefox/Tools > Add-ons > Extensions & Plugins" in case there are still problems.
