At the same time, Red Hat released the first version of Red Hat Enterprise Linux, Red Hat Enterprise Linux 2.1. The Army deployed Red Hat’s operating system in its Blue Force Tracker system, which lived in jeeps and tanks on the battlefield. Major General Nicholas Justice, the man responsible for Blue Force Tracker, said later:

“When we rolled into Baghdad, we did it using open source.”1

To this day, the U.S. Army remains one of Red Hat’s largest customers by volume. Red Hat was recently made part of the Army's Common Operating Environment, which is their enterprise standard.

Using your own domain is a great choice. You should however check whether your domain provider does auto extend the domain name for you, and if not, make sure your contact details are correct so you will get a reminder before the domain will expire after a year.

The other thing is that not all domain names are kind of equal. Some domain names have or had a bad name already when it comes to spam filters. For example IIRC the dot xyz domain names did have a bad name at some point, though maybe not anymore.

Also for serious emailing with companies for example my_name.lol may not be the best choice :-) Then there's the question where to host your email. For example mailbox.org and Tuta do support custom email domains.

LibreWolf comes with uBlock Origin. Your LW installation came without it ? Can you give more details ?
