Comment (by mcs):

 Replying to [ticket:15555 gk]:
 > If I visit foo.com and look at its source (e.g. via Ctrl + U) another
 request is sent over the Tor network using "--NoFirstPartyHost-about-
 blank--" as SOCKS username. There are two things wrong with that behavior:
 1) view-source requests should not hit the network at all as this is not
 necessary.

 It seems like a lot of people agree with you, e.g., see this bug report:
