I’ve assigned domain names using a custom TLD to my home servers for ease of access.

When I put, say proxmox.server, in my address bar, it searches the web. To avoid that behavior, I have to specify http://proxmox.server.

I want Firefox to recognize .server as a valid TLD. I’ve searched the web to no avail, so that’s why I’m writing this.

I came across this post in Stack Exchange, but the method described (ie, network.IDN.whitelist.server) doesn’t work.

Does anybody know how can I add a custom domain to Firefox?
