Topic: Please add Signal Messenger Extension

Please add the Open Whisper Systems Signal Desktop extension. It's still in Beta, but it is extremely secure and will certainly fit your criteria for security. I very much want to use it, but currently it is only available for Chrome or Chromium.

It infact works like a charm, +1 for signal messenger. So much more convenient to tybe on a keyboard than your phone.
