10/23/20 Matt, as of 7:51pm Montana time, I've already tried to remove, then re-install (doing a restart) this to my Firefox browser. Tho I get your little box on Facebook, when I tap the button, all it does is refresh their new page format, but doesn't switch it back, sigh* It worked last night & before even using Windows 7, as I hate their W10. Hoping this isn't a losing Battle.
