In a nutshell, Greasemonkey is an add-on for Firefox that allows you to customize a web site’s look and function. Now you don’t have to be a coder to use it though, because there are already hundreds of scripts out there available for free that you can use to help you do a number of different things.
How Do You Use Greasemonkey?
Once you have installed Greasemonkey, you will see the little monkey’s head come up in your status bar. From here you can create a new user script of your own or you can edit the ones you have already installed. You also have the ability to enable and disable scripts or Greasemonkey all together, if you need to.
Where Can I Find Greasemonkey User Scripts?
Finding Greasemonkey scripts is easy. For that, let me point you in the direction of Userscripts.org. This is a great depository of user scripts people have created to get more out of various web sites. You can browse through all of the scripts, or search for the web site you want to modify.
Greasefire, another extension for Firefox can also help. It will let you know in the status bar how many user scripts are available for that specific URL you are visiting. Here are a few more of my favorite Greasemonkey script collections:
How Can I Make My Own User Scripts for Greasemonkey?
Once you have made a successful Greasemonkey userscript, you might even look into creating it into a stand alone Firefox add-on.
If you like the tweak the Web, and make it your own, then Greasemonkey is well worth picking up as a Firefox extension. The add-on, plus some user scripting can lead to helping you get more out of your favorite web sites, and then share that help with others. When push comes to shove, isn’t that what the Internet should be all about?
