Does WebRTC leak your real IP? How to check and fix a leak webrtc issue?

OP here—thanks for all the replies! Y’all are lifesavers.

I tried ipleak.net, and yep, my VPN wasn’t enough. Disabled WebRTC in Firefox like some of you suggested, and now it’s all good.

Quick Q: Does disabling WebRTC break anything? Like, will sites stop working properly?

Thanks again! 🙌
