Is there a way to log to a console after the extens

Have you tried console.log() with Firebug? (I know you have tried Application.console.log() and Firebug.console.log() already)

I just tried it in the Web Console on FF16 running Firebug 1.10.4 and it seems to work:

Here are some more examples from the Firebug Wiki itself: FirebugWiki Console API

Additionally, you can write messages of different types in the console, such as: console.debug(), console.info(), console.warn(), console.error()
