Additional context

Never encountered the issue with Firefox <85 and Default Bookmark Folder < 3.0 For testing furthermore: I disabled Default Bookmark Folder 3.0, proceeded again to backup to .json file and restored places.sqlite correctly I re-enabled Default Bookmark Folder 3.0, proceeded again to backup to .json file and restored places.sqlite incorrectly again. EDIT: it appears that the Default Bookmark Folder 3.0 extension needs to be disabled only when restoring the bookmarks from bookmarks.xxxx.json file

Importing an HTML file also seemed to be a disaster for one user: https://support.mozilla.org/questions/1323357

Similar here also: When importing .json bookmark from laptop to desktop computer, lots of bookmarks are out of their folder, plus dividers where added everywhere here and there, or folder where moved somewhere else, creating a complete mess. To solve this issue, I deleted the addon (Default Bookmark Folder) and re-import my bookmark again, and everything was perfect. I am using Firefox Extended Support Release version 78.7, on W10. Thank you .

I guess we're all aware that rather than deleting the extension, disabling it is enough, then restore the .json backup (or the html backup). You can then re-enable the extension. No point in removing such a handy piece of work!

You're perfectly right. I'll wait until the problem is fix before reinstalling it. Yes it's a handy piece of work.
