How to Install Firefox Nightly on Fedora 37/36/35

The Firefox Nightly browser is contributed code by Mozilla developers, which is added to a central repository daily, then compiled nightly for developers or enthusiasts to grab the latest edge changes. As the code matures, it then merges into the beta repository. It then 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. The following tutorial will demonstrate how to install the nightly browser on your desktop using the command line terminal and well know third-party COPR repository.
