FAQ

I want Firefox, what is Nightly?

Mozilla's trademarks on Firefox disallows distributing unofficial builds using the Firefox trademark. This is why the Nix-built Firefox is named Nightly.

The official builds are available by enabling unfree and installing firefox-bin.

How do I get Firefox Quantum (57)?

When using NixOS 17.09, stable, nixos.firefox is version 57 as of December 24th 2017. Alternatively,

enabling unfree, and updating channels if required, allows the use of nixos.firefox-bin which is packaged from Mozilla's upstream released binaries.

Using NixOS unstable, the Nix-built nixos.firefox has been updated to 57.

Do note that Quantum is a marketing term, and as long as the version is greater than 57, the enhancements are in the Nix-built browser, which uses the name Nightly because of trademark issues.
