Nightly is working really good in my Android Phone. Now I would like to install Nightly in my LinuxMint Desktop. I found a page at -to-install-firefox-next-beta-or-firefox-quantum-nightly-on-linux-mint/But cannot install with all those commands. So what is the best way to install Nightly on my LInuxMint? Without all the commands and things I don't understand. I am 82 years old and cannot always do such. Thanks for your help.
