Greasemonkey

Modify any website with small downloadable scripts.

Webs and services that Internet put at the disposal of the users nowadays are really complete, nevertheless, there are always small modifications that each user thinks that a website could do with, and that would probably come in very handy if they where implemented, but if these improvements never arrive officially, we will always have the option of installing Greasemonkey.

  This complement for Firefox is extremely useful, even though it can be used for anything on its own, but it does allow to install and launch as many scripts as we want. All the scripts are available on the Userscripts.org website, where we will be able to find thousands of scripts for all kinds of services, from adding buttons to your e-mail server to modify the Facebook galleries, or make the Facebook menus more accessible. There are even scripts that change the full design of a website, like YouTube. As well as the scripts that modify websites, there are also some to automate tasks, very useful in online games that work by means of the browser.

  Once installed, Greasemonkey will show an icon in the Firefox status bar, and if we find any script that we are interested in, we will only have to install it from the web for this plug-in to capture it, and launch it automatically.

  Requirements: This download requires that you have Mozilla Firefox installed.
