Why doesn't my blackbox content scripts work?

I studied the devtools article on Google"s official website, https://developers.google.com..., which talked about breakpoint debugging. I try to debug, but it always jumps to other js files. Later, I learned that I could use blackbox to turn off the plug-in"s scripts. However, I clicked blackbox content scripts, but I still can"t go to the js file I want to see, why?

manually power off debugger in the corresponding place in the js file you want to debug, and see if you can jump to the response page
