Firefox has started using up my available memory significantly slowing other open programs.

When I am doing research or writing I have Firefox open with multiple tabs running as well as Microsoft Office applications. Within a short period of time, the entire computer slows down. System processes show 100% of CPU used with Firefox eating up about 80%. When I close Firefox and then disable that process, all other programs and computer speed return to normal. I'm only using 1/3 of the available memory. I use Windows 7 and have 3g of physical memory.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.
