Stop firefox from displaying the http response and only to display it later?
<p>I'm developing a firefox addon and would like to know if it's possible to stop firefox from displaying the http response while my addon is doing something with the response data? I need the browser to only display the response when I'm done using the response data in my addon.</p>

<p>The flow of my firefox addon is like this:
1) Get HTTP Response but do not display on the browser yet
2) Collect response data using TracingListener
3) Do some computation using response data but no alteration to the response is needed.
4) Display a confirmation dialog box asking user permission to load the HTTP response that is received in step 1.
5) Display the HTTP response on the browser.</p>
