All of those backups are likely the same so there is no need to combine them all unless you want 6 of the same bookmark.

Not sure there is any such utility.
I struggle with all but the simplest of tasks using a sql editor on places.squlite ; and depending on ages there are IIRC two different structures.

I guess in principle the .json files could be stitched together in a word processor. There are .json editors, but I have never tried one.

There is one method you could try, and I have just checked it works with Firefox 23. Open multiple instances of Firefox and multiple instances of the bookmarks library you are able to drag and drop bookmarks between the libraries. Not the sort of thing to try with thousands of bookmarks but may be doable over a few sessions if you do not need to move too many bookmarks.

An alternative Firefox based method. If you do not mind loosing tags and keywords is to export as HTML and then import the HTML. HTML bookmarks append when imported. (.json do not append they overwrite).

I could explain in detail how to do this but it is probably better to see if someone has a more elegant or simpler solution. Any idea roughly how many bookmarks you are talking about in each set, and are many of these duplicated. (you would only need to transfer the none duplicated bookmarks)


Edit related threads

But no sign of a simple solution.

How are those bookmarks organized?

If you only need to consider bookmarks in the bookmarks menu folder a then you can consider to 'park' (copy) them to the clipboard when restoring the next JSON backup and then paste the clipboard content to merge the previously saved bookmarks. I don't know if a copy and paste of the All Bookmarks folder is working properly, but you can give that a try.

Thank you for the suggestions. There is a new issue- on my primary computer there are 2 default profiles in firefox. Each contains a bookmarkbackups folder with files of different sizes, dates and information.

How do I switch firefox profiles? They are in the same user account.

Can I merge the bookmarkbackups without one overwriting the other?

more options

Hi mr91506, you cannot merge the .json files in the two bookmarkbackups folders. If you merge the folders, one of the identically named files will have to be deleted.

You can switch your active profile using Firefox's Profile Manager. This allows you to maintain different profiles (e.g., work and home, kids and parents). But only one can be in use at a time.

Exit Firefox and start up in the Profile Manager using Start > search box (or Run):

firefox.exe -P

Any time you want to switch profiles, exit Firefox and return to this dialog.

When creating a new profile, I recommend using the default location suggested, and to avoid data loss, not re-using any existing folder. Before deleting unneeded profiles, I suggest making a backup first in case something were to go wrong.

By the way, to spell out a previously mentioned approach to gathering all your bookmarks from the old JSON files (https://support.mozilla.org/en-US/questions/968777#answer-470541):

(1) Create a new blank profile

(2) Restore a JSON file (see Restore bookmarks from backup or move them to another computer)

(3) Export the restored bookmarks to an HTML format in a convenient location, with a unique file name (see Export Firefox bookmarks to an HTML file to back up or transfer bookmarks)

(4) Repeat Steps 2 and 3 until you have HTML format exports of all the old bookmarks

(5) Exit Firefox and start up in your normal profile

(6) Import all the HTML files (see Import Bookmarks from an HTML file)

Likely, you will have lots of duplicates, but you will have everything in one place at least.
