1467954 - redirectUrl failed to redirect ws:// to wss:// URL.

Status: NEW

(Core :: Networking: WebSockets, defect, P3)

Description

[u608644]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Build ID: 20100101

Steps to reproduce:

WebExtension's "redirectUrl" can't redirect ws://server to wss://server.

1. Listen ws:// and wss:// using onBeforeRequest.
2. When the requestinfo.destinationUrl includes 'ws://echo.websocket.org', redirect to 'wss://echo.websocket.org' using "console.log('Addon test: fired');return {redirectUrl: wss://...};"


for testing:
http://www.websocket.org/echo.html
ws://echo.websocket.org


Actual results:

(Browser console)
Addon test: fired
Firefox can’t establish a connection to the server at ws://echo.websocket.org/?encoding=text.

Therefore Firefox didn't redirect the request.


Expected results:

Connect to "wss"://echo.websocket.org/?encoding=text as it should be.
Why Firefox is ignoring "return {redirectUrl: wss://xxx};" ?

Thanks for the report John. Could you please add an example test add-on to test with.
