我应该担心“ SecurityError：拒绝访问跨域对象上的属性的权限”日志

Question

我的网站上记录了以下错误，我应该关注还是可以忽略它们？

SecurityError: Permission denied to access property "dispatchEvent" on cross-origin object - url: moz-extension://f985b107-bcb9-45d4-95c4-b1bb39443725/js/inject.js - line: 65 - column: 0 - error: SecurityError: Permission denied to access property "dispatchEvent" on cross-origin object (browser: Firefox 55)

谢谢！

Answer 1

你不应该担心，你可以忽略它们。

它来自火狐浏览器的扩展：url: moz-extension://f985b107-bcb9-45d4-95c4-b1bb39443725/js/inject.js who's attempts to Attach event but CrossOrigin query is not allowed.
