Firefox DNS-over-HTTPS
If you like to adjust Firefox settings, be aware of DNS-over-HTTPS (DoH).
At this time, leave DoH disabled (the current Firefox default). Otherwise, some common "andrews.edu" URLs won't work properly.
About DNS-over-HTTPS
When you type a web address or domain name into your address bar (for example, www.mozilla.org), your browser sends a request over the internet to look up the IP address for that website.
Traditionally, this request is sent over a plain-text connection. Because it isn't encrypted, third parties can easily see what website you're about to access.
DNS-over-HTTPS (DoH) works differently: it sends the domain name you typed to a DoH-compatible DNS server over an encrypted HTTPS connection instead of plain text. This prevents third parties from seeing what websites you're trying to access.
