I want to open a website, change its javascript, then show the website + execute my changed js.
1) Is this possible?
2) How is this possible? ( VB.net, C#, FF + Addons )
Thx in advance
EDIT: To your better understanding, I just want the js to be just changed for my browser output!
You can use Fiddler. This nice software act a http proxy, and provide a script engine that can intercept and transform requests and response. In your case, you can replace on the fly the target javascript content.
