Firefox losing bookmarks

Twice now in the past week I’ve started my computer only to find that Firefox had lost quite a few of my bookmarks. Anyone else run into this? Any ideas how to fix it?

Firefox/2.0.0.15

No one?

Nope. Sorry. I’ve had the same bookmarks for years.

Here are tips from Mozilla on recovering lost bookmarks and preventing future problems including backing them up. I also store my bookmarks at mybookmarks.com and try to remember to update the list occasionally. del.icio.us is a more popular site for storing bookmarks.

I know this used to happen with Firefox 1.x (pre-1.5 I think) which was caused by a new session being opened up when the previous session failed to close down properly and left a phantom task running. This caused the new session to try and access the bookmarks – which were opened in protected read mode – fail, and then kill them and start a new set, killing your old one.

I thought they’d fixed this though. Could be a different problem, but that was the cause of this exact problem in old versions.

The solution was to upgrade to the new version. (3.01 is out, FYI)
