Comment 9 for bug 241609

Unfortunately, I just had this happen again this weekend, so it appears that the bug is not fixed. I copied the old profile and edited profiles.ini as indicated above, and everything worked with the new profile. However, I immediately shut down Firefox and tried to run it using the original (now broken) profile, and the bookmarks were still gone. I am currently running OK with the profile copy, but this indicates that the bug is still around.

It doesn't seem to happen every time there's an unclean shutdown, unfortunately. But, if anyone is interested in generating unclean shutdowns, I get one every time I use Pandora, when the Pandora tab is in the last window I close when quitting Firefox. It seems to close cleanly, but on the next run, I got the "Firefox is still running" message. So, I deleted the '.parentlock' file in the profile directory. After this, Firefox was not able to read my bookmarks; they were not deleted, since the profile directory still contained all the information to restore them.
