I’m having trouble adding pages to bookmarks using Firefox IOS on an iPad. In short, I’m supposed to open the menu bar top right and tap ‘add’ next to bookmarks. Simple. But almost (but not quite every) time I try, there’s no ‘add’, only the bookmark star, which brings up previous bookmarks but doesn't have any way of adding a new bookmark. When I tap ‘done’ the bookmark list closes, but nothing has been added. This is becoming so annoying I’m about to give up on Firefox entirely.
