Comment 6 for bug 1329799

The linked branch has a user script that hides and removes the smart banners generated by the smartbanner jQuery plugin.

The only gotcha with the current implementation is that it doesn’t actually prevent the banner from being instantiated and inserted in the DOM in the first place, it merely hides it, but it cannot prevent the original slide-in animation from starting, which results in the contents of the page briefly sliding down then up again, which doesn’t look too nice.
