+
+`privacy.network` 属性包含了与隐私相关的网络设置。每个属性都是一个 {{WebExtAPIRef("types.BrowserSetting")}} 对象。
+
+这些属性的默认值在不同的浏览器中可能有所不同。
+
+## 属性
+
+- `networkPredictionEnabled`
+  - : {{WebExtAPIRef("types.BrowserSetting")}} 对象，其底层值是布尔值。若为 `true`，则浏览器将尝试通过预解析 DNS 条目、预渲染站点（例如使用 `<link rel='prefetch' …>`）以及预先打开到服务器的 TCP 和 TLS 连接来提升 Web 浏览速度。
+- `peerConnectionEnabled`
+  - : {{WebExtAPIRef("types.BrowserSetting")}} 对象，其底层值是布尔值。若为 `false`，则 [`RTCPeerConnection`](/zh-CN/docs/Web/API/RTCPeerConnection) 接口将被禁用。请注意，[`getUserMedia()`](/zh-CN/docs/Web/API/MediaDevices/getUserMedia) *不*受此设置影响。
+- `webRTCIPHandlingPolicy`
+
+  - : {{WebExtAPIRef("types.BrowserSetting")}} 对象，其底层值是字符串。这一设置将允许用户指定影响 WebRTC 流量路由方式以及暴露多少本地地址信息的媒体性能/隐私权衡。它可以取以下任一值，从最不私密到最私密：
+
+    - `default`
+    - `default_public_and_private_interfaces`
+    - `default_public_interface_only`
+    - `disable_non_proxied_udp`
+    - `proxy_only`（仅允许基于代理的 TCP 连接的 TURN 连接）
+
+- `httpsOnlyMode`
+
+  - : 这一设置允许你的扩展程序确定用户是否启用了 [HTTPS-Only 模式](https://support.mozilla.org/zh-CN/kb/firefox-https)。该属性在所有平台上都是只读的。其底层值是一个字符串，可以取以下三个值之一：
+
+    - `"always"`：HTTPS-Only 模式已启用。
+    - `"never"`：HTTPS-Only 模式已关闭。
+    - `"private_browsing"`：仅在隐私浏览窗口中启用了 HTTPS-Only 模式。
+
+- `globalPrivacyControl`
+
+  - : 这一设置允许你的扩展程序确定用户是否启用了[全局隐私控制](/zh-CN/docs/Web/API/Navigator/globalPrivacyControl)。该属性在所有平台上都是只读的。其底层值是一个布尔值，其中 `true` 表示浏览器发送全局隐私控制信号，`false` 表示浏览器不发送这些信号。

+
+## 示例
+
+设置 `webRTCIPHandlingPolicy` 属性：
+
+```js
+function onSet(result) {
+  if (result) {
+    console.log("成功");
+  } else {
+    console.log("失败");
+  }
+}
+
+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("无法设置 webRTCIPHandlingPolicy");
+    }
+  });
+});
+```
