Happened to me today as well.
Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.3) Gecko/2008092510 Ubuntu/8.04 (hardy) Firefox/3.0.3
Ubuntu 8.04.1 AMD64 Desktop Linux set 2.6.24-21-generic
No bookmarks, empty bookmark bar, and any attempt to restore it (form firefox backup or JSON file) failed.
This was NOT after a unclean shutdown, as I shout off Ubuntu using shutdown button.
I'm NOT using NFS as far as I can tell.
I was NOT out of disk space in /home.
To solve the issue, I copied my .mozilla/firefox folder, deleted old one, and copied the copy back.
This is a serious bug that should be addressed IMHO since the regular user who sees his bookmarks disappear will (and rightly) panic.
I'm available to provide any info you need.
