 causes Tor to be bypassed, and certainly will not be the last one. Since
 these bugs have a very high security impact I propose they are guarded
 against. How about running Firefox inside some kind of firewall that drops
 all network packets not going to Tor?

 Tails now drops all outgoing packets whose destination IP address is not
 RFC-1918 private.  Tails stopped using transparent proxy configuration in
 order to try to keep random crap on the system from linking the user's
 web-browsing activities, but still configures Tor as the GNOME default
 SOCKS proxy, which defeats most of that purpose.

 Tails 0.10.1 allowed traffic to/from RFC-1918 private addresses; I don't
 know whether Tails 0.11 does.
