Are you seeing this if you put your mouse pointer over the microphone: <blockquote><img src="https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-12-26-10-25-26-eca290.png"></blockquote> If I call up Page Info, click over to the Permissions panel, scroll to the bottom, uncheck the "Use default" box for "Use the microphone" and click Allow, then reload the page, the site behaves the same. I think Google doesn't fully support Firefox for its own reasons, whatever those might be.
