There are tasks I frequently perform regarding organization of bookmarks. For example: when I bookmark a webpage, I can only find it by scrolling from the top of the list, passing hundreds of bookmarks I've saved until I get to the end of my list where new bookmarks are placed. While I'm scrolling with my fingers, it's easy to touch some random bookmark since my list is so long. When I return to my list I see I must start at the top again. That's also how I've been instructed that I have to do to search for a bookmarks, if need to find multiple bookmarks there's no way to do it. Firefox for android 80 was clearly still in a beta state. It should never have been released to the public, much less doing so without offering a way to downgrade to a fully functional version. After many years of using firefox, if I can't downgrade I'll be replacing it with another browser.
