If your mimetype settings aren't saving, can you check that mimeTypes.rdf in your profile folder isn't write-protected?

I don't know where to find a "profile" folder. I do not know if it is about mime but I do not know what that is either. Your going to halve to be very specific for me. Just to be clear..When I go to tools/options/content/manage I get the box that says download actions: all the areas are blank and the buttons are greyed out so you cannot change or add anything. It doesn't list a single file type.

What if I uninstall, Run reg cleaner, regedit(delete all mozilla) then re-install?

Comment 4

11 years ago has information on how Firefox uses profiles and how to find your profile folder.

If you are willing to lose all your information, saved bookmarks, passwords and history, you can use the profile manager: to create a new profile and see if the problem persists there.  Alternately, you can can delete the %Appdata%\Mozilla\Firefox\Profiles folder when you uninstall and you'll start fresh when you reinstall.

Bugzilla is really not the best place to ask for technical support, it is a tracking system for actual bugs in various Mozilla products.  If the problem only happens on your computer or with a particular website, you should look into technical support resources. A number of resources are available for Firefox at: .  In particular, you can get help with your question by searching the Knowledge base, or asking on our forums: or using the newsgroup: or using the #firefox IRC chat room: irc://

Please follow up on this issue in one of those places.  Many of the people who help here also provide help in those places and it helps keep bugzilla uncluttered.  If it is determined that it is indeed a bug, we'll have gone through a lot of the troubleshooting and done much of the work to make sure that the bug report is as descriptive and detailed as possible so it can be patched quickly.

Marking INVALID since this really wasn't a bug to start off with.
