Firefox - profile not found

HI there, I am trying to setup firefox-devedition.

{ inputs, pkgs, ... }: {

  programs.firefox = {
    enable = true;
    package = pkgs.firefox-devedition;
    # enableGnomeExtensions = true;
    # languagePacks = [ "en-CA" ];
    profiles = {
      default = {
        id = 0;
        name = "Default";
        isDefault = true;
        extensions = with pkgs.nur.repos.rycee.firefox-addons; [
          # see: https://github.com/nix-community/nur-combined/blob/2691dd44ce8664be1d33f61ed808aca7de38a82f/repos/rycee/pkgs/firefox-addons/generated-firefox-addons.nix
          onepassword-password-manager
          darkreader
          ublock-origin
          privacy-badger
          sidebery

        ];
    
      };

    };
  };

  home.sessionVariables = {
    MOZ_ENABLE_WAYLAND = 1;
    MOZ_USE_XINPUT2 = "1";
  };
}

Now, for some reason, after I rebuild and open the browser, I get: Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I can see my extensions are installed.

seems to have my default profile an ID correct.

Any suggestions?

Thank you.

ah ok. It is the devedition. If I revert to the regular package, the exact same config works.

Still looking for suggestions, but this is a start.

Cheers

No clue,

But you can start it from terminal e check logs?

I had the same. There’s a couple of problems, first the different versions seem to share the same profiles.

pkgs.firefox-devedition uses the firefox executable, which is naughty. Use pkgs.firefox-devedition-bin which uses the correct firefox-developer-edition executable.

Next, to solve the profile issue simply delete ~/.mozilla and try rebuilding/launching again.

Edit: it seems this breaks future rebuilds… back to the drawing board.

On another note, running firefox-developer-edition --profile ~/.mozilla/firefox works just fine, as does firefox-developer-edition -P $username

I also experienced this issue. Switched from firefox-devedition to just firefox to fix it for now, but if someone finds a real fix I would like to use firefox-devedition again.
