What the Google Search Result Sanitizer does is to remove google referer, which is for google itself to record your browsing history, from search result URL's. So that you can get direct link to the result, without delay caused by transition. But now I'm not sure if this is working or not.
I didn't even know that there were shortcuts for Greased Lightbox, I was just pleased that there're something work for Iron. Still it's fine, isn't it?
And also take a look at Facebook Adkiller, it just works fine, well only if you do Facebook.
-I am not a native speaker of English or German, and using Iron as a main browser.
