Hello !

First of all thanks for the code, it helps me immensely in my daily web-browsing activities ! Kudos to you.

However there seems to be something glitchy when used in Firefox with GreaseMonkey, doesn't work at all actually. Is there some blink-specific JavaScript extracts in there that i'm missing ?
