Firefox won't load most pages unless in Private mode. Disabling Add-Ons, Safe Mode, Refresh and Reinstall don't help

Firefox won't load most pages unless in Private mode. Disabling Add-Ons, Safe Mode, Refresh and Reinstall don't help. Sometimes if I let the pages load for like 15 minutes they will, but not always. I have no issues on any of my other computers. No other browsers have any issues. What else should I try?

This article describes what to do if Firefox doesn't open when you click the Firefox icon.

  • If you get a message you can dismiss (e.g. "TypeError: Components.classes['@ ... ;1'] is undefined", "onload error TypeError: ...", "Exc in ev handl: ...") and can open Firefox, see Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems.
  • If Firefox starts but won't load any websites, see Websites don't load - troubleshoot and fix error messages.

The Refresh Firefox feature can fix many issues by restoring Firefox to its default state while saving your essential information. Consider using it before going through a lengthy troubleshooting process. The Firefox Safe Mode window includes a Refresh Firefox option. You can start Firefox in Safe Mode by holding down the shiftkey while starting Firefox.
