Can't scroll firefox bookmarks with mouse wheel

[LWM723]

I have a lot of bookmarks, so that when I open the bookmarks menu, it extends beyond the end of the page. The mouse scroll-wheel should move me up and down, but it doesn't (it doesn't do anything). Interestingly, if I go into a sub directory that also has enough bookmarks to extend beyond the end of the screen, the scroll wheel DOES work normally.

Does anyone know how to fix this problem so that my mouse scroll wheel will let me scroll through my bookmarks?

you have to click "show all bookmarks". the idea of the drop down menu is for people with a normal amount of bookmarks

Why would I wanna show all bookmarks, all the bookmarks are there but I can't scroll down with the mouse wheel. And no, the bookmarks bar is not just for people with normal amount of bookmarks, that's insane! And the mouse wheel scrolling works fine in palemoon and ice dragon with the same bookmarks.
