Msf::Payload::Firefox#read_until_token_source

Javascript source of readUntilToken(s)
Continues reading the stream as data is available, until a pair of
  command tokens like [[aBcD123ffh]] [[aBcD123ffh]] is consumed.

Returns a function that can be passed to the #onDataAvailable callback of
  nsIInputStreamPump that will buffer until a second token is read, or, in
  the absence of any tokens, a newline character is read.
