+
+如果插件可以访问“file://”方案则返回 `true`，否则返回 `false`。
+
+这是返回 [`Promise`](/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Promise) 的异步函数。
+
+## 语法
+
+```js-nolint
+let isAllowed = browser.extension.isAllowedFileSchemeAccess()
+```
+
+### 参数
+
+无。
+
+### 返回值
+
+[`Promise`](/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/Promise)，将会兑现布尔值：如果插件被允许访问“file://”URL，则为 `true`，否则为 `false`。
+
+Firefox 总是返回 `false`。
+
+## 浏览器兼容性

+
+## 示例
+
+```js
+function logIsAllowed(answer) {
+  console.log(`是否允许访问：${answer}`);
+}
+
+let isAllowed = browser.extension.isAllowedFileSchemeAccess();
+isAllowed.then(logIsAllowed);
+```
