Empty Firefox Search Bar

In my 1.5.0.9 Windows version of Firefox, all the search sites in the Search Bar disappeared one day. Didn't realized how much I used that Search Bar until it wasn't functional. I tried reinstalling the app, and when that didn't fix anything, I suspected that the problem was in the user specific application data. I deleted the Application Data\Mozilla\Firefox directory and all my settings got cleared.

I've customized my Firefox so much that it was going to be a pain to redo all the settings and so I restored my settings directory from the trash and proceeded to wade through the Profiles directory and removed one file at a time to figure out which caused the Search Bar to come back.

In the end, it was the localstore.rdf file that turned out to be corrupted. When I removed it, my Search Bar returned to normal. Yay!
