I am able to change and add bookmarks, but these changes are sometimes not saved when I restart Firefox.
Since updating to Firefox 4, changes to bookmarks are saved sometimes after restart, but not usually (maybe 25% of the time). The problem sounds exactly like what is described on the Can't add, change or save bookmarks - How to fix help page, yet after making all the recommended changes, the problem persists. I have also performed the recommended actions on the Changes to toolbars and window sizes are not saved help page, with no luck there either.
The only other thing that I can think of that may be helpful is that I use Firefox Sync between two computers, and both seem to be having this problem.

I have some more information, in case it helps. During one Firefox session, I made about 8 changes to my bookmarks.When I restarted Firefox, the first few changes I had made were saved, but the rest were not. Additionally, the favicons that were present during my last session (that I hadn't had before that session) were reverted to the default favicon. I hope this helps!
