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 but doing this externally doesn't allow me to set breakpoints in the unminified code, for example.
Typical use cases for me:
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.
Someone has made JSBeautifier into a Firebug plugin:

This has made my day today!
