When I upgraded to Firefox 9.0.1 all of my bookmarks were lost, how do I recover my bookmarks?
I had stores, school info.; miscellaneous things, dictionary.com, Google.com, and emails.

A possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.
This turned out to be the root cause for my problem. Simply renamed the places.sqlite.corrupt file to places.sqlite and my profile (including bookmarks) worked again. Thanks!
By the way, I first noticed that something was wrong with my _profile_ when, in addition to lost bookmarks, I noticed that I couldn't create _new_ bookmarks. Also was not able to restore bookmarks from a backup .json file. So I created a new profile, and was able to restore the bookmarks from the original profile's backup. That led me to exploring your suggestion. Thanks again!
