I would have thought that this is the meaning of Bug 388518, but as per Christian Biesinger, I am creating a new issue. I would have thought that the correct way to do this would be to return an nsIHttpChannel for an image request, but if you can think of a better way, that would be great. I am writing a custom extension that reads headers from the image request. Reproducible: Always Steps to Reproduce: See Bug 388518 for an example that demonstrates the problem. 1. 2. 3. Actual Results: No way to retrieve the nsIHttpChannel interface. Expected Results: Expected to get nsIHttpChannel so that I could call methods on it.

What does firebug do?

I'm closing since this is a 2007 extension feature request that isn't being worked on. If there is still the need for this please re-open.
