You can develop Firefox with Nix. https://github.com/mozilla/nixpkgs-mozilla?tab=readme-ov-fil... Then you can use Nix from windows, but im unsure of performance or friction as I've totally abandoned windows personally. Here are some resources: https://nathan.gs/2023/12/14/nixos-on-windows/ https://nixos.wiki/wiki/Nix_Installation_Guide#Windows_Subsy...

Have you taken a look at buildFHSUserEnv[1]? In the Mozilla Nixpkgs overlay it is used to package[2] the Vidyo desktop application. [1] https://nixos.org/manual/nixpkgs/stable/#sec-fhs-environment... [2] https://github.com/mozilla/nixpkgs-mozilla/blob/master/pkgs/...

Looking at the code, I don't see any advantage of using imperative language here. All the conditions used there are already available and don't change during the execution of that code. So the conditionals would be nearly identical in functional language. Nix advantage here would be that is lazily evaluated, so there would be an additional benefit that only conditionals that are used are evaluated. Functional benefit of Nix would be that Nix would know that a package doesn't need to be rebuilt if no inputs changed. Side note Mozilla actually uses Nix internally, it appears that it is used for Rust and Firefox and most likely other things[1][2] [1] https://github.com/mozilla/nixpkgs-mozilla [2] https://github.com/mozilla/release-services

We're defaulting to profile-per-install to make it easier to run different versions side-by-side, but you can still manually specify your original profile. Docs on the profile manager are at https://support.mozilla.org/en-US/kb/profile-manager-create-... ...or, as a super weird hack, you can set the envvar SNAP_NAME=firefox to get the old behavior (see https://github.com/mozilla/nixpkgs-mozilla/issues/163 for context)

Overlays is a way to extend Nixpkgs in a format which can easily be shared, imported and combined. An overlay can add or override packages, like any user could do before with packageOverrides. An example of overlay is the rust overlay provided in the nixpkgs-mozilla[1] repository, which package all latest versions of the rust compiler[2].
