I downloaded the new Firefoxy4, and each time I open it I get a message window that says: Type Error:Components.classes[@mozilla.org/extension/manager:1] is undefined. and asks to press the OK button. When pressed Firefox 4 opens. How do I get rid of the error message?

Keazen oplossing

This is probably due to an add-on that is not compatible with Firefox 4. For details of how to troubleshoot that see https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes
