Take a look at the note from the NoScript developer that was posted here yesterday:
Maybe Google plans to implement the missing stuff later,
maybe they’re still trying to figure out whether it can be
done without enabling effective ad blocking, but in the
meanwhile the pale AdBlock and FlashBlock imitations which
have been hacked together by overwhelming popular demand, are
forced to use a very fragile CSS-based hiding approach,
ridiculously easy to circumvent.
