After this last update Firefox is really slow loading pages and has crashed on me multiple times, I have also noticed if the browser is up it slows other programs down now like when im burning a cd. Is anyone else experiencing this? Thank you

What's your computer system and Firefox version?


Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Basically, an OOM (Out Of Memory) means the system is having issues with the RAM.

You will need a thumb or disk drive to install it on.

Im going to try to do this, but its 100% firefox, any other browser is fine and only when i run firefox do i see one of the tasks under firefox skyrocket in memory usage.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

You can create a new profile as a quick test to see if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
