 > > 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.

 Looking at that bug again I wonder whether our cache isolation is actually
 the culprit here. There are a lot of people claiming we need all caches
 being disabled (which we don't have) in order to hit this problem.
