Mac OS X 10.6.7 (10J869) FireFox 3.6.17 new tabs won't open, just put a new tab on tab bar titled Untitled and cannot switch to the new tab.

Haven't tested all plugins, but firegestures, lastpass don't work.

All worked fine yesterday...

This issue can be caused by an extension that isn't working properly.

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

See:

If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.

  • Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
  • Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
