on newest update Firefox 65.0.2. tabs are back on top and the old userChrome.css does not work.
there is a solution for tabs back to bottom below bookmarks, but that does not work for Multirow Bookmarks

here you find the complete file for download
So did also you post to the site to ask for further help as well? If that was created by a user on that site I would say asking them for help would also be good to do here as well.
Hi, please use <pre> before and </pre> after code blocks to prevent the formatting from getting corrupted.
Also, this seems to be a duplicate of your thread on Reddit: https://www.reddit.com/r/firefox/comments/b1df86/multirow_bookmarks_tabs_on_bottom_for_firefox_65/
