This is still working on most sites (invaluable!) but I've noticed more and more sites it's not working (eg play.com).This is unfortunate as it looks like those sites have so much garbage running with Google etc scripts it's breaking this Addon's code.Hopefully we can have an update soon if the author can afford the time :-)

BTW, this becomes REALLY powerful when used with Context Search https://addons.mozilla.org/en-US/firefox/addon/240
