This is a useful extension. It would be even better if it had some additional feature, i.e.(please take the rows below as suggestions for improvement)
- offer the user to add bookmark to selected folder OR navigate to that folder in the Bookmarks menu.
- offer the user to review/edit additional parameters, such as tags and keywords, before adding the new bookmark.
- search also for already stored bookmark names (and get the container folder from them)


Keep up the good work!
