Websocket TLS

Hello,

My Websocket server recently started failing in Firefox. After some investigation it looks like the issues began in v130. The Websocker server works in all other browsers and in Firefox version <= 129. After much troubleshooting it seems like a change was made to the TLS negotiation when making a Websocket connection. I was able to temporarily solve the problem by forcing TLSv1.2 instead of negotiating the strongest TLS available. Was there a recent change to how TLS is negotiated when making a wss Websocket connection?
