map css with query string

I’m trying to edit live css by mapping my scss preprocess result inside chrome dev tools. I’ve realized, that having css with query string on live sites produces problems. But even disabling query strings,does nothing.

I’ve read this question, but the solution works for wordpress, and as I’ve told – even if my website produces css like :”_css_cscjeofj34j3t9.css” – nothing happens.

I’ve also placed question on drupal stack, but problem concerns chrome dev tools, so maybe here someone knows the answer.

So the right question would be, how to develop css with sources by manipulating local file from outside chrome?
