Hey TerminatorOST, after you left this review I added a relevant snippet to the addon's description. I hope it's helpful!
> NOTE: Disabling WebRTC will break some sites that depend on it, like Google Voice. If you need to use those sites, here's a suggestion from karlbright@: "the best solution for the foreseeable future is to either have another browser (perhaps firefox developer edition without this extension) used for those services, or enable WebRTC, and disable it again once finished."
