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.
