As far as I know the way to get the unmodified source in the Developer tools is to find the html request in the Network tab, click on it, go to the Response tab of the small panel on the right and read the source out of said small panel (it's about 65x11 chars here). I'd much, much rather be able to just hit Ctrl-U and read it in a new tab. If there's an easier way then I'd like to know about it.
