I just updated to Firefox 3.40.5. After I did this all of my bookmarks where gone. I did some goggling which brought me to the places.sqlite file which instead said places.sqlite.corrupt . The first thing I tried was Places Maintenance but that didn't seem to do anything. I then tried replacing it with a previous version but the same thing happened when I opened Firefox. I tried crating a new profile and completely reinstalling but ever time I open Firefox it changes to places.sqlite.corrupt and a new places.sqlite is created. It seems to me it must be something caused by the update. Everything was fine till then. Is there a way to rollback the update? What else can I do?

Thanks
