Even before the bits have dried on Firefox 15, Mozilla want to talk about Firefox 16. One of its big "innovations" is a command line for debugging but this isn't your father's command line - it's all new and reinvented.
Firefox 16 is still in the beta channel, but you might want to check out its new developer feature - a command line. It doesn't add much that is completely new, just a keyboard-oriented way of getting at the existing developer tools.
If the idea of going back to a command line is something that fills you with dread, the good news is that this is a re-invented command line with lots of assistance.
