How do I force "other bookmarks" to show up in the bookmarks MENU (frustration caps, sorry), and not in the bookmarks toolbar?

How do I make "other bookmarks" show up on the bookmarks menu? (Not the toolbar, thanks). Basically for me, the bookmarks toolbar is just too much valuable real estate in the window. I keep it turned off. Until a year or two ago I could access "other bookmarks" in the bookmarks menu -- in fact I still can at my wife's home computer. (Oddly, she keeps the bookmarks toolbar turned on, so if I needed to get to other bookmarks at home it wouldn't be much trouble anyway.) I've hunted around on the internet and found nothing but advice on how to use "other bookmarks" on the toolbar, which is what I'm trying to avoid. A helpful AI (hahahahaha) suggested that turning the "OB" off on the toolbar would leave me "still" able to access them on the menu, but that didn't change anything on the menu. Thank you in advance!
