Is there any IE11 extension to modify header same like Mozilla with modify header?
I would like to know more about IE 11 extension that can actually modify header manually. Basically I need to modify header and pass as "Referer" to spoof if we arrive on the webpage from that referer!
You could install Fiddler and modify request headers with the CustomRules.js file
To modify the header with Fiddler:
1- Open Fiddler Web Debugger and in the menu toolbar go to Rules->Customize Rules... (shortcut is Ctrl + R). It opens the CustomRules.js file. Fiddler may suggest you to download Fiddler ScriptEditor but you can edit it with any text editor (I use notepad++)
2- Find OnBeforeRequest(oSession: Session) in the script file.
3- You can add a new header by adding oSession.oRequest["NewHeaderName"] = "New header value"; to OnBeforeRequest function. Also, to remove a header, use oSession.oResponse.headers.Remove("HeaderName"); function.
