My bookmarks disappeared two days after installing new version. When I try to restore from an older backup it says "unable to process the backup file." When I try to restore bookmarks from a newer version it says "Unsupported file type."

Your System Details shows;

Mac OS X 10.10
Firefox 31.0

Why are you using such an old browser?

Firefox 32+ switched from regular .json files to compressed .jsonlz4 files. That could be why Firefox 31 can't handle the newer format.
