Snowflake works in Linux, not in Windows

I’m using Firefox in both Linux (Debian 13) and Windows 10. Snowflake works properly in Linux, but doesn’t seem to work at all in Windows. Firefox’s configuration, add-ons, etc., are the same in both OS.

Can you suggest something I should check or a possible solution?

check WebRTC on the Windows side first, snowflake can’t connect without it. a WebRTC test page failing there would explain it even if the add-ons match.

This page reports as follows:
