+
+返回当前扩展内运行的每个页面的 [Window](/zh-CN/docs/Web/API/Window) 对象数组。例如，这包括：
+
+- 后台页面（若定义了）
+- 任何弹出页面（若定义并已加载）
+- 任何选项页面（若定义并已加载）
+- 任何托管了扩展打包内容的浏览器标签页
+
+在 Firefox 中，如果从隐私浏览窗口的页面调用此方法，例如从隐私窗口中的侧边栏或从隐私窗口打开的弹出窗口，则其返回值将不包括扩展的后台页面。
+
+## 语法
+
+```js-nolint
+let windows = browser.extension.getViews(
+  fetchProperties // 可选的对象
+)
+```
+
+### 参数
+
+- `fetchProperties` {{optional_inline}}
+
+  - : 包含如下属性的对象：
+
+    - `type` {{optional_inline}}
+      - : `string`，指示要获取的视图类型的 {{WebExtAPIRef('extension.ViewType')}}。如果省略，此函数将返回所有视图。
+    - `windowId` {{optional_inline}}
+      - : `integer`，要限制搜索范围的窗口。如果省略，此函数将返回所有视图。在 Firefox 版本 92 及更早版本中，侧边栏视图并不匹配，因此将不会被返回。
+
+### 返回值
+
+`object` 数组（`array`）：[Window](/zh-CN/docs/Web/API/Window) 对象数组。
+
+## 浏览器兼容性
+
+{{Compat}}
+
+## 示例
+
+获取属于此扩展的所有窗口，并记录它们的 URL：
+
+```js
+const windows = browser.extension.getViews();
+
+for (const extensionWindow of windows) {
+  console.log(extensionWindow.location.href);
+}
+```
+
+仅获取托管了扩展打包内容的浏览器标签页中的窗口：
+
+```js
+const windows = browser.extension.getViews({ type: "tab" });
+```
+
+仅获取弹出页面中的窗口：
+
+```js
+const windows = browser.extension.getViews({ type: "popup" });
+```
