Mozilla developers contribute code to a central repository every day. This code is compiled nightly to create a pre-release version of Firefox for testing. The code matures and then merges into stabilization repositories (Beta and Dev Edition). The code is polished until it reaches a level of quality that allows for a new final version of Firefox to be shipped to hundreds of millions of people. Nightly builds are an essential part of the Firefox development process, as they allow us to test new code and ensure that it meets our high standards before it is released to the public.
Often, non-developer users should refrain from using the nightly version, given it can bring either system instabilities but, more often, features that may not be secured or open new security issues. For example, one would never do internet banking on a nightly browser. However, checking out the nightly version may be interesting for users that like upstream versions of the latest bleeding-edge software and are casual browsers.
The following tutorial will teach you how to install Firefox Nightly on Fedora 36 Linux using a COPR repository using the command line terminal.

Once launched, you can continue using the browser as you would with any other, do note you can get involved more if you would like by following the browser prompts such as visiting the developer channel, feedback, etc.
How to Update/Upgrade Firefox Nightly
For future updates, since you have installed the software from a repository, run the standard DNF commands to check for an update manually. You should be notified along with the rest of your system updates, given that it is a DNF install.

Lastly, if you have no intention of re-installing, you should disable the COPR repo.
sudo dnf copr disable proletarius101/firefox-nightly -y
