Standard diagnostic - Firefox From MozillaZine Knowledge Base This article provides a standard set of steps to follow if Firefox is no longer working properly, and offers solutions that will preserve your user profile data (bookmarks, passwords, history, preference settings, etc.) as far as possible. You should first search the Knowledge Base and check the links given at the end of this article for a solution to your specific problem. Important: The Firefox configuration, bookmarks and other personal data, and information on themes and extensions are stored in your profile. Uninstalling and reinstalling does not change the profile data, and therefore may not solve the problem.
