 Noticed this while testing out some new webextension changes on Firefox.

 I get the following errors:
 {{{
 Snowflake: WebRTC DataChannel opened! snowflake.js:1154:13
 Firefox can’t establish a connection to the server at
 wss://snowflake.bamsoftware.com/?client_ip=45.72.156.47.
 snowflake.js:1090:11
 Snowflake: websocket-relay error. snowflake.js:1154:13
 Snowflake: websocket-relay closed.
 }}}

 This are reproducible with a clean master branch.

 I'm also getting several bootstraps to 10% during my client tests that
 aren't going through my proxy so I'm guessing others are having the same
 problem.
