This addon is GREAT! It's the first one, out of several I've tested that, according to browserleaks.com/webrtc, actually works! Local, Public and IPv6 IP Addresses are all listed as, (n/a)! Give this addon a go! (Recommended by someone who cares about online privacy!)

Works like a charm according to https://browserleaks.com/webrtc

Ok

a very good extension on webrtc protection for firefox up until now.
it should be one of those "must have extensions" for firefox.
many thanks to developer for this extension.
