I downloaded the tar to my user account Downloads dir, unpack and run from there. Created a launcher in KDE. I use Help > About and it checks for updates, pulls any and updates and tells me to restart Firefox, works great. Wish Mozilla would put Firefox in Ubuntu repos like Thunderbird. Makes me wonder if Mozilla gets a kickback from Canonical to diss Ubuntu users and make them think snap is the only way to run Firefox.
