When I updated to Firefox 9.0, all my bookmarks were wiped out, and all bookmarks I attempted to make after the update have not been added. I have to start from zero every day.

Perform the suggestions mentioned in the following articles: * [[Bookmarks not saved]] * check to see if Firefox's [[Lost Bookmarks#w_default-set-of-bookmarks-is-shown-in-bookmarks-folder|Default set of bookmarks is shown in Bookmarks folder]] -> Locked or Damaged ''places.sqlite'' * http://kb.mozillazine.org/Locked_or_damaged_places.sqlite Check and tell if its working.

If you use cleanup software like CCleaner then check the settings for the Firefox application.
