Probably because NetworkManager has capabilities for setting static
wired connections, and for setting hands-off on DNS entries.  The
Firefox maintainers have chosen to assume that most users are not
going to mess with the innards of networking scripts, and that letting
NM manage connections is the most prudent move if you have to make one
choice for everyone.  People who like to mess with innards will
undoubtedly figure out how to change configurations.  The number of
users who would be baffled by delays in browsing when their connection
drops likely far outnumbers those who would be stymied by Offline Mode
in this case.
