Opening Links with Firefox
If you use Discord and it silently fails to open links in Firefox, you possibly have encountered 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-
This should print a few store paths, focus on their ends, which should look like nss-x.xx. We're interested in the one with the newest version. Next, create a new file called discord_patched.nix and paste the following code into it:
with import <nixpkgs> {};
pkgs.discord.override {
nss = pkgs.nss_3_49_2;
}
Now replace nss_3_49_2 with the previously looked up version's "attribute name", which you can look up here. Finally, build and install this patched package with
$ nix-env -i $(nix build discord_patched.nix) --arg config '{ allowUnfree = true; }'
Log in again and you should be able to open links properly.
