To add to this, disabling WebRTC when you're not using it (media.peerconnection.enabled in Firefox) is also a good idea as when it's enabled websites can use it to derive your IP address behind a proxy/NAT such as a VPN or a home router to better identify which machine you are. I also turn off WebGL (webgl.disabled in Firefox) because it seems to expose a large attack surface for fingerprinting* but I'm not too well versed on the exact risks of it.

ublock has an option to disable webrtc ip leak without disabling webrtc entirely.
