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.
