If you use this plugin and have noticed an abrupt decrease in Chrome's performance, this extension is likely the root cause. For the past two weeks, Chrome has been incredibly slow and almost impossible for me to use. I disabled my plugins one by one and found out this was the culprit.
Great. Just this work for me. Thanks.
能用，但有 bug。 根据源码分析： 1. 因为加载 config 是异步的，导致应用规则在读取配置之前，因此配置功能完全失效。而默认规则是 '/.*/'，虽然有效但会导致所有网站的跨源检测都失效，而部分强制检测的则直接报错。 2. 代码中硬编码了 config.arrayUrlRegex[0]，因此只有第一个规则起作用，第二个和之后的规则都没作用；虽然 (1) 中导致了 config.arrayUrlRegex[0] 总是 '/.*/'…… 3. 如果有什么网站遇到 cors 问题又安装了此扩展，必是此扩展的问题。
Doesn't Work document.getElementsByClassName('myiframe')[0].contentWindow.document Uncaught SecurityError: Failed to read a named property 'document' from 'Window': Blocked a frame with origin "https://xxxxxxxx.com" from accessing a cross-origin frame.
Love it. Use it almost everyday for development.
部分网站有用 有得没有用不知道为啥

有用！
Good extension, but please, make it disabled by default. Whenever I reopen Chrome, extensions turns on, which makes browsing Internet unsafe (because, well, that's what this extension about).
It's disabled by default, but when you click the big green enable button, it works like a dream.
