that is a lot of lost bookmarks

Yeah, and a lot of research gone, and a lot of work to get them organized, I still have most of them in a local backup… 😮‍💨

the bookmarks continue past the bottom of the screen

Yeah, lol… In my case you have to scroll down to see other subfolders, which contain more subfolders and finally you get a list of Bookmarks that < again > goes off the screen…
