Since I "upgraded" to FF 4, I have constant crashes (I tried updating my graphics drivers--it did not help) and now all of my bookmarks have disappeared. When I try to restore them, I get this error message "Unable to process the backup file". I have lost years of bookmarks...please help.

I am using Windows XP, SP 3 if that matters.

I am also unable to restore any of the backups of the bookmarks, both automatic backups and two backups that I created manually. Since I was able to restore backups before, and since no changes have occurred to these backup files, the problem must be with Firefox.

Right before my bookmarks disappeared, FF crashed and I accidentally started FF 3.5. When I saw what I did, I ended the Firefox process and started FF 4. That's when all my bookmarks were gone and I discovered I couldn't retrieve any backups. I did note that an add-on was updated when I restarted FF. Maybe that's the problem. Does FF have a Safe mode?

It turns out that the add-ons and extensions are not the problem.

I opened FF 3.5 and couldn't retrieve them into that program either.

Would somebody please help? I have three years worth of bookmarks, and I can't remember them all.
