"The bookmarks and history system will not be functional" error message

I'm definitely giving up although I'm convinced about Mozilla values... The The bookmarks and history system will not be functional" error message is really driving me nuts! I followed first your "Fix..." instructions; it worked for a few days, and then back again without any bookmark. After that, all of a sudden, miracle! I got back all my bookmarks without any action! Today, once again, I've been waiting for weeks for my bookmarks to be available on Firefox... I imported them to Edge and I'm now using Edge.

You can check for problems with the places.sqlite and favicons.sqlite files in the Firefox profile folder.

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

If errors are reported with "Verify Integrity", close and restart Firefox or reboot the computer 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 backup in the bookmarkbackups folder via the Bookmarks Manager (Library).

You can use the button in "Help -> More Troubleshooting Information" (about:support) to go to the current Firefox profile folder or use the about:profiles page (Root directory).
