I am using NixOS with Gnome, and would like to set Chromium as the default browser.The 'Details' section of my settings, under 'default applications' shows the following:Both Chromium and Firefox have been installed on my system (Chromium via $ nix-env -i chromium), and yet they do not show up under the drop-down for 'Web', which shows only the one option.How can I set Chromium to be my default browser?
How to set the default browser in NixOS?
gnome3;chrome;nixos
NixOS does not manage user-specific configuration. Full-stop.As for the browsers not being found by the configuration dialog, try installing them via /etc/nixos/configuration.nix instead of with nix-env.TipIf you install packages declaratively and imperatively you'll end up having to manage two dependency trees. One via nixos-rebuild --upgrade boot and another by nix-channel --update && nix-env -u. Meaning that if you forget either update process you'll end up with old packages installed.
