Hi Andrew,

thanks for catching this!

F37 currently reads:

"The browser must be able to send streams and data to a peer in the 
presence of FWs that only allows http(s) traffic."

Would a change to:

"The browser must be able to send streams and data to a peer in the 
presence of FWs that only allows traffic via a HTTP Proxy."

be correct?

Br,
Stefan
