If you use Sync then best is to disconnect Sync temporarily during troubleshooting.

This could be a problem with the places.sqlite and favicons.sqlite files in the Firefox profile folder.

• use the "Places Database" -> "Verify Integrity" button on the "Help -> More Troubleshooting Information" (about:support) page

If errors are reported with "Verify Integrity", close and restart Firefox or reboot and retry.

If "Verify Integrity" cannot repair places.sqlite, rename/remove all places.sqlite and favicons.sqlite files in the Firefox profile folder with Firefox closed. Firefox will rebuild places.sqlite and restore the bookmarks from the most recent JSON backup in the bookmarkbackups folder.

• keep a backup copy of places.sqlite in case a new places.sqlite database has to be created
• you lose the history when a new places.sqlite is created

You may have to restore an older bookmarks backup in the bookmarkbackups folder via the Bookmarks Manager (Library).

For some reason all our bookmarks has disappeared on August 29th. I tried everything out there to resolve the problem but there's nothing, they disappeared and they aren't saved anywhere on my PC. It is funny because I thought they were saved, and according to all the support and problem solving pages I googled it's suppose to be in my PC but they are not.

Hello, I tried everything. There's absolutely no bookmarks anywhere on my PC. I read somewhere that Mozilla has a back up on their end. I'm wondering if this is true.
