Create your own entry in the right-click menu. Add custom scripts, links, sub-menus or custom CSS 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.

Apply custom CSS styles on the current page based on the page you're visiting. Make them always apply or only when you toggle them on. Create comprehensive changes using a CSS editor with lots of features in the application or simply use your editor by using the CRM External App (source, app). If you want you can also download userstyles from userstyles.org and you can even export your stylesheets as userstyles.

Run your own javscript scripts on the current page or simply use ones that someone else wrote by sharing them. You can also write the javascript in the extension itself or use your own editor with the external editor app (source, app). Apart from using standard javascript you can also access the Custom Right-Click Menu's own APIs allowing you to extend the menu through your own code which simplifies creating self-contained scripts or sub-menus of course featuring a permissions system for any external scripts to make sure they don't spam your menu with copies. Next to this you can access almost every single chrome API without having to go through the hassle of creating a chrome extension specifically for it. This allows you to easily increase your productivity by for example automatically creating bookmarks, managing your tabs or even setting alarms. If you're using chromeOS this becomes even better since then you can even change things like your wallpaper and things about your system itself. Apart from creating your own scripts you can use other people's scripts and share your own. Using a very secure system that allows you to manage a script's permissions no harm can be done.

Create your own menus that are relevant for their own situations. For example, create a menu that lists all frequently used search engines and allows you to add one using a javascript snippet. Making menus and changing where they are visible allows you to make a specific right-click menu for every page and re-use other menus, even being able to show different menu items based on the content you clicked on (page, link, selection, image, video or audio).

The new live version can be found here.

Clone the repo, run npm install and run the grunt "build" task, load the extension into chrome from the "build/" folder.

You can develop scripts both inside the extension and outside of it. By using the external editor you can edit in your preferred editor while still having the changes sync up to the extension. Editing inside the extension features code completion by CodeMirror and Tern on both the CRM API and regular browser functions.

The CRM API allows you to edit the current state of the context menu right from a running script. This allows you to do things like create an "add website to menu" button, removing or adding subsections in a menu or even communicating with other running scripts. By also using a background script (which runs at all times and uses the same permissions/API), you can do pretty much everything a chrome extension could. The CRM API also features full compatibility with the GreaseMonkey API, so you can use all userscripts.

There is a typescript definition file available for the CRM API over here and you can find both an in-extension and online version of the documentation. The in-extension version can be found by going to /html/crmAPIDocs.html or by hitting the "go to definition" key in the CodeMirror editor.

To install the extension for contributing, simply clone this repo, run npm install, and load the extension into chrome from the "app/" folder. You should be able to have your changes in the app folder be reflected to live instantly by hitting ctrl/cmd + r on the options page. Building isn't really necessary as long as you don't need to export the files as it basically only compresses and removes unnecessary files.
