Firefox on Android not working on mobile data

Firefox on my android phone times out on any webpage whenever I am not connected to a Wi-Fi. All webpages and IP addresses timeout with no response. Same issue occurs on Firefox Beta app and Firefox Nightly. All other applications work as expected with full internet access on mobile data. The same pages/addresses respond as expected on Chrome and the built-in browser.

Simply put, all Firefox apps have no internet connectivity on mobile data.

Solutions I've attempted with no success or change: Re-install Firefox. Logging out of Firefox Sync. Clear Firefox data and cache. Disabling tracking protection. Disabling HTTPS-only mode. No proxy settings are enabled. Confirmed Firefox application has mobile data network privileges. Disabling, re-enabling mobile data network privs. Installing Firefox Beta and Firefox Nightly; same issue.

Another possibly related issue: Firefox does not follow routes from a Cisco AnyConnect VPN on my phone. Opening pages/IP addresses routed through the VPN are rejected or timeout as if the VPN is not active at all. The same pages/addresses respond as expected on Chrome and the built-in browser. This occurs over Wi-Fi as well, of course nothing works on mobile data as described above.

Device: Oneplus 8T (KB2003) OS: OxygenOS 13.1 (Android 13) Firefox version: 117.0.1

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
