privacy.network

The privacy.network property contains privacy-related network settings. Each property is a types.BrowserSetting object.

Default values for these properties tend to vary across browsers.

Properties

networkPredictionEnabled
A types.BrowserSetting object whose underlying value is a boolean. If true, the browser attempts to speed up web browsing by pre-resolving DNS entries, prerendering sites (using, for example, <link rel='prefetch' ...>), and preemptively opening TCP and SSL connections to servers.
peerConnectionEnabled
A types.BrowserSetting object whose underlying value is a boolean. If false, the RTCPeerConnection interface is disabled. Note that getUserMedia() is not affected by this setting.
webRTCIPHandlingPolicy
A types.BrowserSetting object whose underlying value is a string. This setting allows users to specify the media performance/privacy tradeoffs which affect how WebRTC traffic will be routed and how much local address information is exposed. It may take any one of the following values:
"default"
"default_public_and_private_interfaces"
"default_public_interface_only"
"disable_non_proxied_udp"

Examples

Set the webRTCIPHandlingPolicy property:

function onSet(result) {
  if (result) {
    console.log("success");
  } else {
    console.log("failure");
  }
}

browser.browserAction.onClicked.addListener(() => {

  var getting = browser.privacy.network.webRTCIPHandlingPolicy.get({});
  getting.then((got) => {
    console.log(got.value);
    if ((got.levelOfControl === "controlled_by_this_extension") ||
        (got.levelOfControl === "controllable_by_this_extension")) {
      var setting = browser.privacy.network.webRTCIPHandlingPolicy.set({
        value: "default_public_interface_only"
      });
      setting.then(onSet);
    } else {
      console.log("Not able to set webRTCIPHandlingPolicy");
    }
  });

});
