How to capture traffic without disconnecting from Freenode IRC?

[freenodeFiddler]

I use Fiddler to debug HTTP requests for a browser extension, but I found out whenever I start capturing traffic, I would immediately get disconnected from Freenode IRC.

 

How should I set Fiddler up, so that it can ignore any incoming and outgoing traffic to Freenode IRC, while allowing me to capture other traffics for the browser extension? I'm assuming by ignoring the traffic to and from Freenode, I wouldn't get any disconnections.

 

If I am wrong, can someone explain why it is happening, and what is the recommended way to prevent this from happening?

 

Thanks.
