I’ve made a script to install Firefox Nightly with little hassle on Linux distributions that do not have it in their standard repositories.
First, you should view the script before executing it:
curl https://aranym.com/nightly.sh | less
To download and run this script, execute this:
cd; curl -LO aranym.com/nightly.sh && bash nightly.sh
If you have any issues, contact me on Discord.
