I had a very unusual problem this AM. On computer start up all my FF settings, preferences, tool bar settings, homepage were lost and FF reverted back to it's default settings. My bookmarks were still there. I've never seen that before. I did a system restart and still the same thing. So I had to reset all the settings and preferences. Nothing odd with my IE9 browser. I did a security sweep and everything was normal. Anybody seen this before?

Hey there, do you also still have your history, cookies and passwords intact? If yes, this sounds like someone activated Firefox Reset on that computer. In any case, you should be able to find your old profile on your computer still as Firefox reset just creates a copy and leaves the old profile as it is. You can use this article to locate your profile, and it also links to the profile manager to switch profiles: Profiles - Where Firefox stores your bookmarks, passwords and other user data

Thanks for the reply. Everything was intact except for FF defaulting back to it's default settings. I'm the only one on this computer so it did it all by itself. It took about 15 mins to reset everything. Really strange.

Maybe Firefox didn't close properly that last time and some files like pref.js and localstore.rdf got corrupted

Try to use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.
