You can also just download the tar ball from Mozilla and run that. It takes care of keeping itself up to date. I do that on Manjaro because I want my updates straight from the source. I'm on the beta channel, so my browser updates frequently and it simply indicates when there is an update and then I can choose when to restart the browser. Works on Ubuntu as well.

That's what I do currently. But updating itself does not work. Maybe because I did not install it as root?
