Host permantly replace? Help me?

[Djoowie]

Hi,

 

I was playing around with fiddler and its scripts while Steam was running.

The first page I saw was my Trade Offer page and I wanted to replace that with my own Website just to mess around.

What I did was: 

if(oSession.uriContains("/id/zwifs")) {
            oSession.host = "coddr.net";
        }

 

And I did not what I wanted it to do so I removed it and saved..... Now I have the issue that in the Steam client the page constantly becomes my won website: coddr.net

And I want that to be removed, I tried to do 

if(oSession.uriContains("/id/zwifs")) {
            oSession.host = "steamcommunity.com";
        }

 

And it works but when I close down the software its somehow coddr again. How can I fix this?
