iOS Firefox needs to maintain bookmarks hierarchy state (i.e. keep bookmark folders collapsed or revealed based upon users’ preference) when organizing bookmarks. Like many other Firefox users, I have a lot of organized bookmarks. And, when iOS Firefox opens my complete bookmark hierarchy, it’s a pain in the butt to locate folders in which I want a new bookmark to be placed. If iOS Firefox could maintain my bookmark hierarchy state (like Firefox desktop), I could organize bookmarks so much more easily & efficiently. Incidentally, I submitted this idea several years ago and never received any feedback or action.
