Mozilla introduces Firefox Nightly RPM package repository

Mozilla has announced
a repository with Firefox
Nightly channel packages for RPM-based Linux distributions such as CentOS
Stream, Fedora, and openSUSE. Mozilla has provided a Debian repository
since 2023.

Note that this repository only includes the nightly builds of The
firefox-nightly package. Mozilla is not providing stable
builds as RPMs at this time. However, the package will not conflict
with a distribution’s regular firefox package; both packages
can be installed at the same time for those who wish to test the
nightly builds. See the blog post for instructions on setting up the
repository.
