speedtest.im Not working properly when enabled

[People-11]

This site uses special ways to anti debug:

1. The site obfuscated its javascript
2. The main js will get an error with this extension enabled
3. If not using this extension, using 'Deactivate Breakpoints' instead, the webpage will fall into a trap - both CPU and memory usage become abnormally high, making the page laggy and impossible to debug
