Useless Rated 1 out of 5 stars
Thanks for the effort, but sorry, this extension is pretty useless and has brought back nothing.
You get the exact same result by choosing "Manage Bookmarks" in the menu and selecting the specific folder.
The sense of the older "Manage Folders" extension/versions as written by Jed Brown was that you can open DIFFERENT folders that are in the Bookmark menu SEPARATELY.
This is what really made the old versions useful.
