I HAVE TRIED TO FIND A STREAMLINED WAY TO DELETE MULTIPLE DUPLICATE BOOKMARKS (UNINTENTIONALLY CREATED BY AN OLDER FIREFOX BOOKMARKS IMPORT). BUT I HAVEN'T FOUND ANYTHING THAT WORKS. USING BOOKMARK MANAGER IS FAR TOO TEDIOUS AND TIME-CONSUMING. AND AN EXTENSION ADD-ON I TRIED CREATED EVEN MORE PROBLEMS. I NEED HELP!!

I am used to having a Firefox for my personal Mozilla account, bookmarks and sessions, and Firefox Developer Edition to be logged in my work account, where I could use everything I need to work in a separate environment.

Recently I changed a job. Logged out past-job@mail.com from Firefox Developer Edition, logged in with present-job@mail.com and... I still can see old bookmarks.

- I cleared history and new bookmarks: nothing
- went to about:preferences#privacy and clear all the data: bookmarks still there
- tried Help > More troubleshooting information > Refresh Firefox…: all the same
- reinstalled firefox@developer-edition with brew: nah
- eventually, logged out from presetn-job@mail.com in Firefox Developer Edition and personal@mail.com in Firefox; uninstalled both, deleted everything related to "mozilla" and "firefox" was able to find in my system: unsuccessfully

The last thing I didn't try yet is burning my laptop in favor to a new one.

Where are those bookmarks? Why nothing is helping?

When I discover that I have already bookmarked a URL, I want to easily discover in which of my folder(s) I have saved the bookmark. In some cases, the hosting site morphs the bookmarked URL with a redirect, so I am unable to discover the containing folder by browsing to the URL. Sigh. I would also like to discover situations where I have already bookmarked a single URL in several different folders.

I have downloaded the JSON for my bookmarks file and parsed the JSON. I now know that I have 7388 URLs bookmarked which are saved across 111 folders.

I am having trouble discovering the parent/child relationships between the various folders in which the bookmarks are saved. I have several situations where child folders have the same names and can be identified only when the child's parent folder is known.

Undated Firefox documentation at [https://developer.mozilla.org/en-US/d.../BookmarkTreeNode#parentid] suggests that each node in the bookmark tree should have a parentid and an index. I see an index but I do not see a parentid. I do see a GUID field. I have seen comments suggesting that parentid has been replaced by GUID.

But the values I see (GUID=FqNNI0k91ZjW, for example) do not make sense and have no connection to the ID fields (ID=2658, for example).

Can anyone help me make sense of the GUID values I am seeing? Are GUIDs now being hashed for some reason?
