I get (Firefox 140.4.0esr):
tcp        0      0 192.168.1.100:51410     151.101.81.91:443       ESTABLISHED

The "about:networking" page lists
"content-signature-2.cdn.mozilla.net" which resolves to
34.160.144.191. Also "firefox.settings.services.mozilla.com" and
"firefox-settings-attachments.cdn.mozilla.net" which are
151.101.81.91:

So Mozilla's using Google and Fastly as hosts for services Firefox
is connecting to automatically. However in the past I've tried to
block these mystery services from connecting, so thanks for the
tip. Also a connection to a government website that I haven't even
visited for weeks! I really which I could ditch FF and just use
Dillo.
