On a few sites, the pages load very slow (minutes). I had the exact same problem (same pages as well) on another computer and fixed it by formatting/installing windows 8. I'd like to avoid formatting this computer. It loads much faster in IE.

What I have: Windows 7 (all updates), Firefox 21

What I don't have: antivirus software special firewall settings

What I've tried: Uninstall (everything in Firefox), reboot, reinstall Firefox Remove cookies, history Safemode run Unchecked hardware accel

Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.

Download a fresh Firefox copy and save the file to the desktop.

Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.

  • Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will lose all personal data like bookmarks and passwords from profiles of other Firefox versions.

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

  • (32 bit Windows) "C:\Program Files\Mozilla Firefox\"
  • (64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"

Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

If you keep having problems then also create a new profile.



Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.

Removing folder did not help. Giving up and formatting. I assume this problem only effected older Firefox versions. No worries, it's a great product and I'll continue to use it. With Firefox and Noscript, I've been virus-free for years.

Sadly I cannot try that as everything is working perfectly after the format. Thanks though.
