Comment (by dcf):

 I suppose a workaround is to change the phony addresses in the bridge
 lines (0.0.2.0) to something else. 0.0.0.0/8 satisfies
 `tor_addr_is_internal` which is what
 23b088907fd23da417f5caf2b7b5f664f317ef4a is checking for.

 I tried editing
 Browser/TorBrowser/Data/Browser/profile.default/preferences/extension-
 overrides.js in an already installed Tor Browser and changed 0.0.2.0 to
 1.2.3.4. That made it work.

 The phony IP address can be almost anything. It is completely ignored. The
 reason it is not 0.0.0.0 is because tor uses 0.0.0.0 to mean "not set"
 internally. The reason it is not 0.0.0.![1-255] is because addresses of
 that form have a special meaning in SOCKS4a. 0.0.1.0 was used for flash
 proxy (another transport that ignores the address you provide it).
