For those who are interested to know what is greasemonkey, read this intro taken from that book.

Greasemonkey
reasemonkey is a Firefox extension that allows you to write scripts that alter the web pages you visit. You can use it to make a web site more readable or more usable. You can fix rendering bugs that the site owner can’t be bothered to fix themselves. You can alter pages so they work better with assistive technologies that speak a web page out loud or convert it to Braille. You can even automatically retrieve data from other sites to make two sites more interconnected.

Greasemonkey by itself does none of these things. In fact, after you install it, you won’t notice any change at all… until you start installing what are called “user scripts”. A user script is just a chunk of Javascript code, with some additional information that tells Greasemonkey where and when it should be run. Each user script can target a specific page, a specific site, or a group of sites. A user script can do anything you can do in Javascript. In fact, it can do even more than that, because Greasemonkey provides special functions that are only available to user scripts.
