The nix expression also installs a desktop item as another option for starting the application.

== Opening Links with Firefox ==

If you use Discord and it silently fails to open links in Firefox, you possibly have encountered [https://github.com/NixOS/nixpkgs/issues/78961 issue #78961]. This is caused by a version mismatch between the NSS libraries used by Discord and Firefox. Luckily, a relatively easy workaround is available:

First, find out which NSS version Firefox is currently using with

$ nix path-info $(which firefox) -r | grep nss-

</syntaxhighlight>

This should print a few store paths, focus on their ends, which should look like <code>nss-x.xx</code>. We're interested in the one with the newest version. Next, create a new file called <code>discord_patched.nix</code> and paste the following code into it:

with import <nixpkgs> {};

pkgs.discord.override {

nss = pkgs.nss_3_49_2;

}

</syntaxhighlight>

Now replace <code>nss_3_49_2</code> with the previously looked up version's "attribute name", which you can look up [https://nixos.org/nixos/packages.html?query=nss_ here]. Finally, build and install this patched package with

$ nix-env -i $(nix build discord_patched.nix) --arg config '{ allowUnfree = true; }'

</syntaxhighlight>

Log in again and you should be able to open links properly.
