Is there a plugin that allows me to automatically unminify the Javascript included on a site?
Is there a plugin, add-on, Greasemonkey script or something similar (at worst, an easy to use proxy?) that automatically **unminifies** the Javascript files included on a site?

I know about e.g. [jsbeautifier.org](http://jsbeautifier.org/) but doing this externally doesn't allow me to set breakpoints in the unminified code, for example.

Typical use cases for me:

 - Analysing and learning from complex web frontends.
 - Debugging Greasemonkey scripts which interact with the existing code.

I'm primarily interested in a solution that works with Firebug, but if there's something for the dev tools of Chrome or Opera, I'd like to hear about it as well.
