Sometimes mty firefox will get messed up and I wont have my bookmarks anymore. I think it creates a new profile or something. How do I change profiles in firefox and get my bookmarks back?

the best thing to do is to sign off on the screen name you are using, that will normally restore it when you sign back in. but if you search on the internet it will tell ya where to look for them, some where in your profiles it says bookmarks, but i am not sure where
