+获取浏览器操作的用户设置。
+
+> [!NOTE]
+> 该 API 在 Manifest V3 或更高版本中可用。
+
+这是一个返回 [`Promise`](/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Promise) 的异步函数。
+
+## 语法
+
+```js-nolint
+let userSettings = await browser.action.getUserSettings();
+```
+
+### 参数
+
+无参数。
+
+### 返回值
+
+一个 [`Promise`](/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Promise)，会兑现包含下列属性的对象：
+
+- `userSettings`
+
+  - : 包含由用户指定的浏览器操作设置的对象，具有下列属性：
+
+    - `isOnToolbar` {{optional_inline}}
+      - : `boolean`，用户是否将该操作的图标固定到浏览器 UI。这一设置并不能指示操作图标是否可见。可见性取决于浏览器窗口的尺寸以及浏览器 UI 布局。
+
+## 示例
+
+以下代码输出指示操作是否被固定的信息：
+
+```js
+function gotSettings(userSettings) {
+  if (userSettings.isOnToolbar) {
+    console.log("操作被固定到工具栏");
+  } else {
+    console.log("操作未被固定到工具栏。");
+  }
+}
+
+let gettingUserSettings = browser.action.getUserSettings();
+gettingUserSettings.then(gotSettings);
+```
