Recovering an accidentally deleted bookmark subfolder
I migrated to Win10, installing Firefox and restoring bookmarks from a json file. I subsequently spent some days reorganizing and editing the bookmarks but inadvertently deleted a large subfolder from these. Of the number of options to get that back I see there are 10 or so recent bookmark backups I can try restoring from. The folder I want exists in one of those, but I will also have lost many recent edits. Is there perhaps a way to view both bookmark trees side-by-side, or a way to restore bookmarks selectively or to a different location than the bookmark root?
(I know I can back up what I have now, restore an older version, manually copy out the missing folder, restore my new version and reinsert the lost data, but hoping for less work)

The name of automatically created JSON bookmarks backups 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. You also see this count in the Library, Restore menu drop-down list.
- bookmarks-YYYY-MM-DD_<item count>_<hash>.jsonlz4.
You can look at this tool to inspect a compressed jsonlz4 bookmarks backup and possibly convert this file to HTML to be able to import/merge bookmarks.
I could not get that reader page to load my .json file using either drag-drop or browse. My attempt to copy and paste the missing folder from an older html backup to a newer one just made a bigger mess with lots of duplication. It does say "DO NOT EDIT" in those files, so I shouldn't be surprised.
I was able to restore one of the bookmark autosaves from a few days ago that gave me back that huge subfolder I was missing, so I guess I will just repeat my recent edits on that.
Create a new profile and launch it, restore the bookmarks backup there, then drag and drop the desired folder into your main profile.
Good idea, that would be the simplest way....but
When I tried this I could copy-paste a small number of bookmarks between profiles, but I could not copy-paste or drag-drop anything containing folders. It also seems to be picky about where you can paste to - I could not paste to a folder icon, only to the actual area where a bookmark should appear. I was pasting to the bookmark manager view to keep it from jumping around.
After the edits looked good I deleted my temporary profile and restarted FF. I had a scary moment when it appeared to open a default themed profile instead of my customized main one. Another restart and the theme and tabs of my main profile showed up. Not sure what was happening there.
