Don't forget about this; "media.peerconnection.enabled = false" WebRTC leaks IP when you use TOR/VPN, test it with ipleak.net "beacon.enabled = false" Blocks

Don't forget about this; "media.peerconnection.enabled = false" WebRTC leaks IP when you use TOR/VPN, test it with ipleak.net "beacon.enabled = false" Blocks https://w3c.github.io/beacon/ https://w3c.github.io/beacon/ analytics. Also recommend using plugins; uBlock, NoScript if you use VPN.

How can WebGL leak your IP? Did you confuse it with WebRTC?

That is really disappointing. Particularly for firefox with their supposed focus on privacy, to enable a service that leaks ip when I run a vpn, contradicting the plain intention of the user, shocks me.

Firefox doesn't necessarily know that you're using a VPN, so it's not really contradicting "plain intention". The problem is the way that WebRTC works; it has to have access to this information in order to function. The real issue is that there should be a prompt guarding this information, the way there is when a website requests your location. Hopefully this can be fixed. Also, for what it's worth, Firefox lets you disable this, but I don't think Chrome/Chromium let you disable it at all: https://productforums.google.com/forum/#!topic/chrome/gJ8HF-yoG-Y https://productforums.google.com/forum/#!topic/chrome/gJ8HF-...

    ff doesn't know I'm not using a vpn, so they shouldn't add features that leak ip addresses and a setting buried in a pile of configuration is the same as it not existing for 99.99% of users

> "media.peerconnection.enabled = false" WebRTC leaks IP when you use TOR Tor Browser disables this by default and if you're using Tor over standard Firefox you already have far bigger problems.

Just tried it on ipleak.net, it seems WebRTC only leaked a local IP address, so if you're behind a router, it's almost meaningless… Until there's an attack involving a device on your local network.
