Firefix 119.0.1 on Android connecting to wrong port on proxy server

As of yesterday (1st Nov 2023), Firefox started reporting "Proxy Server Refused Connection" when trying to browse websites over Wifi.

I have a proxy server configured in my phone wifi settings, and this has worked before, and still works in other apps (Chrome, etc)

Checking with tcpdump on the proxy server itself, I see my phone trying to connect to port 80, rather than the configured port (8000)

Firefox version: 119.0.1 Phone: Samsung Galaxy S22 Android version: 13

Chosen solution

I've switched to using the 120 Firefox Beta, and it's now working.

That will do as a work-around until it's fixed on 119, or 120 is released.

Update: reconfiguring the proxy to also listen on port 80 is a temporary workaround. Not a long-term solution though.

Thank you for letting us know, hopefully this is included in Firefox for Android 120 which is due out very soon.
