I recently switched to Firefox and imported all of my chrome bookmarks. When I open the Bookmarks viewer (Ctrl-B) in the sidebar or the Library ("Manage Bookmarks"/Ctrl-Shift-O), the "Bookmarks Menu" folder contains all of my properly organized bookmarks in a tree of subfolders, just like I expect. But when I open the "hamburger" menu on the upper-right corner and select Bookmarks, It only shows a list of "Recent Bookmarks" (along with some options to manage bookmarks). I tried using the "Customize Toolbar" feature to add the Bookmarks Menu to the toolbar, but when I open it, it just shows the same thing as if I had gone through the hamburger menu. I tried looking through Settings, but I couldn't find an option to access my "Bookmarks Menu" from a dropdown menu instead of having to open the sidebar or the Library every time. Is there something I'm missing?
