I am new to Chrome extension development. I'm going to make an extension that will do nothing but replace the original window.Websocket class with a third-party one. To achieve that, I think I need to execute window.Websocket = ThirdpartyWS before every page is loaded.
I didn't read all the documents. I don't know how to execute an extension. I have thought about background script, and content_scripts, but none of them can satisfy me.
