Extensions Context Menu API is available starting in Dev 6.0.472.0

The full API documentation may not be up yet in the extensions developer documentation (but it should be available soon), but you can peruse the Trunk documentation which includes an example at:

http://src.chromium.org/svn/trunk/sr...xtMenus/basic/

To use the Context Menus API, you will need this permission:

"permissions": [ "contextMenus" ]

Thanks for pointing this and the cookies stuff out, been looking forward to this one.
Sooooo glad the create isnt asynchronous anymore, it was hell
