Started Firefox up this morning and my bookmarks are missing... attempted to restore and they won't restore

Started Firefox up this morning and my bookmarks are missing... attempted to restore and receive an error that the bookmark backup can't not be restored. I tried to restore several of the backed up bookmark files and they errorred.

I can't even save a bookmark either to even recreate my bookmarks... Any help is greatly appreciated.

What about the rest of your profile? Settings, bookmarks, history, passwords . . . .


Let's start with, If you have sync, and there is a problem anywhere, Shut Down Sync Immediately On All Devices to prevent the problem from spreading. Once the problem is fixed, perform the same repair on all computers/profiles before using sync again.


[v57+] Places Maintenance is built into Firefox.

Type about:support<enter> in the address bar.

You will find Places Database near the bottom. Press the Verify Integrity button.

If any errors are reported, check this link: https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional

The places.sqlite file contains your History and Bookmarks. And it looks like it is corrupted.

Type about:support<enter> in the address bar.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Locate the above file. Then rename or delete it. Restart Firefox. The browser should then create a new place.sqlite and recover your bookmarks from the backup files.

Note: Your history is not backed up and will be lost.

Before deleting any files, I suggest doing a regular shutdown and restart of Windows to release file locks and resolve any transient permission/privilege issues that could be interfering with Firefox working with the places.sqlite and favicons.sqlite database files.
