I keep receiving this message when I run mozilla firefox for win7 "what happened:TypeError: Components.classes['@mozilla.org/extensions/manager;1'] is undefined"
Whenever I open Firefox... an error pop up window appears with this message "what happened:TypeError: Components.classes['@mozilla.org/extensions/manager;1'] is undefined"

This issue can be caused by an extension that isn't working properly.
Start Firefox in Use Troubleshoot Mode in Firefox to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
- https://support.mozilla.com/kb/Safe+Mode
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")
In Firefox 4 you can use one of these to start in Safe mode:
- Help > Restart with Add-ons Disabled
- Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)
Many thanks. It's solved. Cheers!
