do you depend on your history data? otherwise we could try to purge the database that holds your bookmarks & history and restore the bookmarks from a backup...

in regards to the addons you could try this: go to the firefox menu ≡ > help ? > troubleshooting information > profile - show folder... then window should open up containing your profile folder. in there look for the files named extensions.ini, extensions.sqlite, extensions.sqlite-journal (and in some cases also extensions.txt, extensions.rdf). delete or rename those files and quit firefox, they will be regenerated the next time you launch firefox.

hello, when you type about:sync-log into the address bar and open the latest one or two error logs, can you copy their contents and put them into http://pastebin.mozilla.org/ or a similar service and paste a link here on the forum? this would be very helpful in assessing the problem. thank you!

thanks, so apparently the bookamrks & addons engine is failing during synchronisation. i see that you have the "places maintenance" addon present, did you have issues with database corruption in the past already?

I got the "places maint" as a means to try and fix this problem...when I ask it to run it often just sits there "executing maint" but never finds anything wrong. I will run again now. Thank you for your help. Hopefully we can figure this out...I've been doing all that I can all weekend to fix.

No, I do not depend on history - just bookmarks.

I went through profile. Found a extensions.ini folder and deleted

ok, then while in your profile folder, please also make a backup of all files starting with "places" in a safe location and then remove it from the profile as well.

afterwards you could restore them from your last backup like described at https://support.mozilla.org/en-US/kb/restore-bookmarks-from-backup-or-move-them#w_restoring-from-backups
