14/01/2020: Firefox binaries now available
Binaries for Firefox are now available in the official repositories
under the package name firefox-bin.
This allows you to remove Rust, cbindgen, GTK+2, Python 2, nodejs, Clang and never have to build or install them again.
Those who would still rather build their own Firefox are able to do so
by installing the firefox package.
KISS also now tracks the Extended Release versions of Firefox which update less often providing less of a burden each update.
