I have a Chrome extension that I constantly use for debugging HTTP services. I would like to take screenshots of what I see but usually it has more than I can see on my screen (there is a scrollbar on the right). On a normal website I would use something like Screen Capture by Google but all such extensions work with regular websites only. I assume it has something to do with security.
Is there a setting to enable these extensions work on pages I want? Or maybe there is an app that can save these pages as either an image or pdf?
