My bookmarks seem to have disappeared between when I shut down Firefox last night and today - and when I go to restore to a previous date, I get "unable to process the backup file" How do I fix this?

Opened Firefox - all bookmarks gone, nothing in history. Nothing backed up. As I attempt to restore, none of my restore points can be accessed, I get error message that says: "unable to process backup file" What has happened? Everything worked fine yesterday - and I have performed no updates.

It's actually quite simple to restore your lost information. Hover your Firefox Menu Tab and click the Bookmarks Menu. The little box will pop up. Click on Import and Backup ... the second option down is "restore" . Hit that and it should give you a list of dates that Firefox auto-saves your bookmarks. Just pick a date and apply. If this doesn't help. You may have to revert to an earlier version or check your addons.
