Greasemonkey: very handy firefox addition¶

I've heard it mentioned a few times, but I've finally gotten around to trying it myself: greasemonkey . It is a sort of framework that allows you to load in javascript files that modify certain webpages. There's a whole collection of scripts available. A few favourites:

• AutologinJ, which automatically enters your login info if you've got that stored for a certain website. You can exclude/include websites. Very handy for your adwords account.
• Google access keys for ctrl-. and ctrl-, (or alt-) browsing between result sets in google.
• The best: Google search keys which numbers your google search results. Just press the number on your keyboard and you're taken to that page. Absolutely great.
• Cross amazon, which allows you to switch from a book's page in one amazon to another. I've changed the script to just switch between amazon.de, amazon.co.uk and amazon.com.
