I’m currently taking a look at Greasemonkey scripts in general. I always thought that it would be to complicated to install and use them which is absolutely not the case to my astonishment.Look it up is another Greasemonkey script that can be installed like any other Firefox extension. It becomes active once you reboot Firefox and works twofold. First you mark a word or phrase in Firefox and hit a key afterwards to send a request to a dictionary site such as wikipedia.
