My bookmarks have all disappeared and it says one of Firefox's files is in use by another application. I have followed the troubleshooting steps and deleted the places. I have uninstalled and reinstalled firefox. I have tried to restore from backup, both the automatic history and a saved json file and it says it can't process either backup file. What do I do to get my bookmarks back??

What security software do you have?

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
