firefox - Run context.drawWindow method through a bookmarklet -

I want to capture a webpage as an image. I'm able to do this by using the Firefox extension by using the context.drawWindow method. Now I want to straighten myself and see if I can do this by using the bookmarklet):

I remember reading reference reference works only from the Firefox (Firefox) tool. I do not know whether it is still true or not.

Can I leave any light if I can execute context.drawWindow () from a bookmarklet or not?

Thank you Kapil

You can not, because with the permissions of the bookmarklet page Let's go, and Dunduwondo is Chrome-only (only used by Firefox UI and Extensions, not web pages).
