I simply want to merge all of my different .json Bookmark files into one but I can't find a solution anywhere. I have so many of these because each time I have to reinstall windows I save my bookmarks and each time there are different bookmarks built up but there are many duplicates. Please help me find a solution because I can't figure this out.

Are these files from one profile, or several?

Firefox automatically creates a backup of the current bookmarks file. If you were to combine these files, you would end up with a large amount of duplicate entries. Is there something in the backup you want back?

I have several .json bookmark back up files from each time that I reinstalled windows on my pc I would back up the bookmarks and each time I added different bookmark links. There has to be a way to merge all of them and I will deal with the duplicates on my own. I am more than willing to look through each one and delete the duplicates one by one, I need to merge all of them into one convenient file.

Sorry, Firefox doesn't "merge" .json backup files and I have never seen an external program that will do a "merge".

bookmarks.html files do merge when you import.

The only way to merge multiple JSON backups would be to backup the current bookmarks to an HTML file after each restore and import all those HTML backup afterward.

A possibility would be to extract all links from such a file and place them in one HTML file. but you would lose the folder structure doing this.

There are methods described in this MozillaZine forum thread to extract links from from a bookmarks JSON backup.
