Question

JavaScript

Hello. Is it possible to change the JavaScript file of the called page using the Chrome extension in the same way as with the developer panel?
For example - to replace several functions in it. Thank you.

Answer 1

Yes, you can.
Or through content scripts that will modify the source code of the page.
Or through interception of js files and their substitution.
