My bookmarks disappeared from my Firefox Sync.

Posted

The only ones left are the mobile bookmarks. All my desktop bookmarks I had categorized into folders are gone.

Try to restore a JSON backup.

  • Bookmarks -> Show All Bookmarks -> Import & Backup

The name of a JSON bookmarks backup file includes a total item count (folders and separators included) and an hash value to prevent saving the same backup more than once.

  • bookmarks-YYYY-MM-DD_<item count>_<hash>.jsonlz4.

You may have to restore an older JSON backup manually if recent JSON backups are already affected.

If you use Sync then best is to disconnect Sync while performing maintenance/repair efforts to files in the Firefox profile folder.
