Please allow users to tap and hold a bookmark to drag it to a custom position. This should be possible on the app too. The Chrome app has had this function for years. For some reason Firefox limits us to alphabetical or chronological order in the app. There is now also a "sort by custom order" option, but this only seems to shuffle around my bookmarks to a random order!! Please sort out custom bookmark reordering in the app once and for all. Otherwise great app.
