Many comments from non-NoScript users
For all those who claim Opera does the same as NoScript already, you've clearly not tried it.
I use Opera and Firefox daily, and last week installed NoScript (due to hype read on El Reg), which does far more, far more easily, than Opera does via the preferences.
I've turned NoScript off, however, because there are virtually no sites on the internal the are usable with it fully enabled, so the default action for every page had become "load page - enable scripts", and the only advantage left was blocking google ads.
