Hi: Can anyone help me to recover BOOKMARKS which I've found missing after today's starting my Firefox Browser/Thunderbird and trying to use one of the BOOKMARKS: this is for the first time I've lost them just by opening the Program after I've about 3 weeks ago Upgraded my Windows 7 to Version 10 - under Windows 7 they were working properly without any 'accidental loss'. Question: - is it possible to use the Bookmarks-Back Up file to re-install them - IF NOT, what is the other way to reliably re-install them ...? My PC-system is: Windows 10 Home, Ver 10.0.19042 (20H2), CPU; Intel Pentium D 935 3.20Ghz (dual core), x64-based processor, 32-bit. I'd greatly appreciate any SPECIFIC INSTRUCTIONS how to accomplish this. Tony H.

Hi thorsak

Thank you for your question.

What is the full filename of the "Bookmarks-Back Up file" that you have? Is it something like "bookmarks-2021-06-17.json"?

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

This can be caused by a problem with the places.sqlite and favicons.sqlite databases in the Firefox profile folder.

  • use "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 a 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 can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
