Err didn't Microsoft get slapped down for this?
When Microsoft decided to do a similar thing with IE10 (do not track) did they not get shot down and told it would be ignored?
I assume the firefox method is going to be more direct. Rather than a request it will outright just block the nasty practices?
Serves the ad slingers right IMO. Lets's hope they all start blocking it (hmmm Chromium)
