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. Iftrue
, 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. Iffalse
, theRTCPeerConnection
interface is disabled. Note thatgetUserMedia()
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"

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"); } }); });
