FF29 fails to load Session Manager, old tabs, any add-ons, Cool Preview, etc after forced upgrade on an XP system. Connecting to sites, especially support.mozilla.org requires numerous retries. Clicking Add0on shows none of the previous working ones. They are gone. No Session Manager at all. Even reporting this has taken over 3 hours. Yesterday, everything worked fine before the restart to 29. What can be done to recover settings from 2-3 days ago? Thanks for keeping it simple!

Thank you for your question. Once history is gone, there is not a big chance of getting it back. However there are some places to check. For next time, try to backup your profile http://kb.mozillazine.org/Profile_backup.

The crash reports from your troubleshooting information is caused by a hang in the Flash plug in version 13. I understand however that this is an issue with the history.
