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. 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

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, from least private to most private:default
default_public_and_private_interfaces
default_public_interface_only
disable_non_proxied_udp
proxy_only
(only connections using TURN on a TCP connection through a proxy are allowed)
httpsOnlyMode

"always"
: HTTPS-Only mode is on."never"
: HTTPS-Only mode is off."private_browsing"
: HTTPS-Only mode is on in private browsing windows only.
globalPrivacyControl

true
indicates that the browser sends Global Privacy Control signals andfalse
indicates the browser does not send the signals.

property:
js
function onSet(result) {
if (result) {
console.log("success");
} else {
console.log("failure");
}
}
browser.browserAction.onClicked.addListener(() => {
let 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")) {
let setting = browser.privacy.network.webRTCIPHandlingPolicy.set({
value: "default_public_interface_only"
});
setting.then(onSet);
} else {
console.log("Not able to set webRTCIPHandlingPolicy");
}
});
});
