Why won't firefox PERMANENTLY delete a bookmark?

I have been attempting to delete duplicate bookmarks from the bookmarks toolbar in Firefox. They almost instantly reappear. I have turned off bookmark syncing, yet they still come back. I have uninstalled/reinstalled Firefox to no avail. I have tried following other suggestions about that ugly little bookmark star thing to no avail.

I have been working as a software engineer for more than 35 years. This uncontrollable application behavior is unacceptable. To purposefully hide a setting for changing this behavior is what I euphemistically refer to as STUPID! "Usability" my rosy red patootie.

Please tell me how to PERMANENTLY remove a bookmark from Firefox. Until this started, I liked Firefox over the other browsers but I am at my last straw here before permanently uninstalling Firefox itself.

Are you still connected to Sync?

If you use Sync then best is to disconnect Sync on all devices while performing maintenance/repair efforts to files in the Firefox profile folder.

Reconnect one device at the time and wait for the initial Sync to finish before connecting another device once you have fixed the bookmarks.


Note that there are backup available in the bookmarkbackups folder.

The name of an automatically created JSON bookmarks backup in the bookmarkbackups folder includes a total item count (folders and separators included) and an hash value to prevent saving the same backup more than once.

  • bookmarks-YYYY-MM-DD_<item count>_<hash>.jsonlz4.

Hi there - try the following add-on: https://addons.mozilla.org/en-US/firefox/addon/bookmark-dupes/

If this solved your problem, please mark as solution.

Tried it. No luck.

Thanks, though! :-)
