That looks great, thanks. Installing it now! I've been burned in the past by relying on extensions like these, which only work until Google change their HTML and then the extension author is (understandably) burned out and doesn't update the extension, and eventually I just give up and uninstall it... I'd be a lot happier if this was a core Google Search feature. But I understand that Google don't make money by blocking their (paying) customers (spammers who run ads) from their search results.
