Greasemonkey for beginners

“If you’d like to try your hand at Greasemonkey hacks, read on
to see how it works!

“Greasemonkey user scripts are the bits of code that actually do
the work – Greasemonkey itself just loads and manages these.
User scripts are written in JavaScript, but be warned: for security
reasons, this isn’t just a question of writing regular JavaScript
and away you go. There are some gotchas to be aware of, although
the scripts in this tutorial don’t encounter any of them.

“A quick note if you’re unfamiliar with JavaScript: this
tutorial isn’t going to explain JavaScript syntax in any detail,
but don’t let that stop you from giving it a go. It’s all fairly
logical and the code snippets are all explained.

“To install a script that someone else has written, you navigate
to its location in Firefox and click on the link to the script.
You’ll get an install popup, as with a normal extension, and can
either look at the source code of the script first or, if you’re
feeling trusting, just install it.”
