Please explain the problem in detail. What happens? What is/are the exact error message(s) ?

I hope you can help.

I have gotten so confused about my bookmark problem.

I used to be able to select "bookmarks" and I had a choice to move a bookmark to one of my "bookmark files". That option is now GONE. I can only save to "current bookmark tab" which is no help. I then need to select "edit this bookmark" and move it to the proper file.

I need to make to Bookmark selections to bookmark one site. It's driving me crazy and I know everyone else has the same problem but no one has an answer that I know found.

Thank you for your help.

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. Type https://accounts.firefox.com/settings<enter> in the address box. 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 box.

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

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

The places.sqlite and favicons.sqlite files contains your History and Bookmarks. And it looks like they are corrupted.

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

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 files. Then rename or delete them. 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.
