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: 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.

thanks for the reply, yet it still does not fix the issue with deleting bookmarks under other bookmarks from the address bar or bookmarks stored in the bookmark toolbar that are to the left of the other bookmarks folder. edit bookmarks is also unresponsive when right clicked

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Hi levisguy,

In addition to the advice given here, I'm unclear about how you're determining that the function does not work. Does the item still appear in the bookmarks menu?

Hallo Chris,

i'm not sure how much clearer I can be.

I. i go to either the the bookmark toolbar drop menu or the other bookmarks folder in the menu bar.

II. I right click on a bookmark that I wish to remove.

III. I left click remove said bookmark, the bookmark is NOT removed.. this is applicable to every bookmark

i did the reset that Fred suggested and I just tried the troublshooting. the issue persists. i thought perhaps it was due to the use of norton's vpn, but that was not the issue either.

Are there errors reported if you use "Verify Integrity" on the "Help -> More Troubleshooting Information" (about:support) page ?

Did you try to rename/remove places.sqlite and possibly favicons.sqlite and let Firefox create new files ?

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

You can check for issues with the places.sqlite and favicons.sqlite databases 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).

• Bookmarks -> Show All Bookmarks -> Import & Backup -> Restore

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.

In addition to cor-el's advice, could you try the solutions in the following article, and see if any of them help: Can't add, change or save bookmarks - How to fix

nothing that has been suggested has done anything to fix the issue

Would you mind sending us a video of what you're seeing?

not possible

Would you be willing to have a call on Zoom or something else, where we can see you recreate the issue and help troubleshoot it? There must be some detail we're missing.

Hey Chris,

I got so fed up with nothing working that I just uninstalled firefox and reinstalled it. i can now delete bookmarks from the bookmark toolbar and other bookmarks. prior to this, I tried to do a browser refresh that didn't do anything to fix the issue.

That was very good work. Well Done. Please flag your last post as Solved Problem as this can help others with similar problems. Go to that post and click the 'Solved' button to its right.
