Firefox wont let me restore my missing bookmarks

more options

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."

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

If you had trouble finding the current installer, see:
