With the latest version, what I would like to call the Best Google Chrome Version ever, the Google Browser now supports Greasemonkey scripts natively. Some of you might be jumping with joy now, and for others who are wondering what this stuff means, here is a small intro
What is Greasemonkey
Greasemonkey is a Firefox extension  that allows developers to customize web pages using simple JavaScript. Greasemonkey can be used for adding new functions to web pages (for example, embedding price comparison in Amazon.com web pages), fixing rendering bugs, combining data from multiple webpages, and numerous other purposes.

So, What’s the Deal ?
If you read carefully, on Firefox, you need to install an extension before you add any Greasemonkey script. However, Google Chrome has this feature “inbuiilt”, ie, it works without installing any extension. there’s over 40,000 scripts on userscripts.org alone. You can install any of them to your Chrome Browser too !
Installation is quick and easy, just like installing an extension. That’s because under the covers, the user script is actually converted into an extension. This means that management tasks like disabling and uninstalling work just like they do with extensions.
Note that user scripts are powerful software and have full access to your private data on any web site. So, for example, they could read all your web mail or access your online bank. Be sure to read the comments on any user scripts in order to decide whether you trust the author with this power.
