Recommendations For Mozilla Firefox versions prior to 43.0, update to version 43.0 or later to resolve the issue. For Firefox ESR versions 38.x prior to 38.5, update to version 38.5 or later to resolve the issue. As a temporary workaround, consider disabling WebRTC functions until a patch is available.
