@leocg I wouldn't be asking if I could. It might be possible but the point is I don't know how to because when I hit the bookmarks button I'm presented with Bookmarks bar, Other Bookmarks, and New Folder (as well as some not relevant to the question). When I click "Other Bookmarks", unlike with every other browser in existence, it does not drop down to show every subfolder so I'm unable to save it in a specific location, only the root folder which isn't what I want.

I imported my bookmarks and they're neatly organised into different folders for different categories, but when I try to bookmark a new site I'm only presented with "other bookmarks" and can't access the folders.

Let's say I have a bookmark folder for books, how do I bookmark a site in the books folder, please?
