Custom Right-Click Menu от Sander Ronde

Create your own new entry in the right-click menu. Add custom JavasScript scripts, links, sub-menus and custom CSS stylesheets that activate when you click them in your right-click menu and do anything you want all from your right-click menu. Featuring full GreaseMonkey compatibility for userscripts and Stylish compatibility for userstyles.

Note: This extension does not allow you to remove right-click menu entries as some people seem to think.

Using the CRM API, the chrome APIs that come with it, and the background script, you have the same freedom in writing JavaScript scripts that you would have writing a chrome extension except that this is a lot easier. This allows you to write just about anything you want and incorporate it into your or someone else's right-click menu by sharing it.
