I installed this add-on to get rid of that annoying new "Other Bookmarks" folder that makes itself the default bookmark location with no setting to change the the default back, or delete this useless folder Mozilla has imposed on me even though I don't want and will never use it. I don't know whose idea that was, but I don't appreciate it.

This add-on allowed me to designate my Bookmarks menu as the default folder again, and save bookmarks to the end of it when I forget to choose a subfolder for them. That is what I have been doing for about 15 years, and it works just fine for me - I know where to look for a bookmark if it isn't where it's supposed to be, and I no longer have to change the default top level bookmark folder EVERY SINGLE TIME I create a bookmark.

In case you can't tell (LOL), I am pretty pissed that I had to install an add-on to accomplish what used to be default behavior (way too much of that with Quantum), but given that I do, I very much appreciate that there IS such an add-on. Thank you.
