I imagine the user would change the start page to about:blank, then
open the firewall, then everything works as normal.
Of course, this only works for single-user machines. A multi-user
machine wouldn't protect the second user to run Firefox.
In the days of CDN's and other tricks to deal with no more IPv4 ips you
can't block *.mozilla.org without also blocking everything from CNN to your
local bank. The ips may change all the time or they may be leased to
someplace for a short time.
