Take a screenshot of a webpage with JavaScript?

Firefox has a "drawWindow" method on the canvas element that lets you copy a screenshot of the window into a canvas element (from where it can then be extracted). This is however not enabled for webpages (only for add-ons), because it forms a security risk: http://mxr.mozilla.org/mozilla/source/content/canvas/src/nsCanvasRenderingContext2D.cpp#2352

In short, plugins (or activex components) are the only sure way to go. Browsers aren't going to provide this as standard functionality because the risks outweigh the benefits.
