When using a remotely-hosted web application using "HTTPS":

FireFox does not allow insecure websocket connections by default.  For more information, follow the link below:

  

Why are some browsers giving "SecurityError" when using loopback as the URL?

A workaround for FireFox is to change an internal configuration within the browser. Please do so at your own risk, and note that FireFox warns this may void your warranty and can cause other unwanted or unexpected behavior.

Follow the instructions below:

  

1. Open up FireFox

  

2. In the URL, type in "about:config"

  

3. A warning screen will appear. Click the "accept" button to proceed.

  

4. Using the search text box, search for "insecure"

  

5. Locate the option "network.websocket.allowInsecureFromHTTPS"

  

6. Toggle this option to "true"


Toggling this option to true should allow insecure websocket connections when using a web-application hosted remotely using HTTPS.
