Since Firefox 16 we have the new cool developer command line which e.g. allows me to take a screenshot of the current page.

Now instead of pressing Shift+F2 and then typing

screenshot --fullpage --clipboard 

manually each time, it would be nice to have a bookmark that does this.

But I can't find a way how to call such a command without actually opening the commandline.

I would have hoped for some kind of special "protocol", so I could type in the URL bar something like: commandline:screenshot (similar to about:config)

Or as an alternative: is it possible to call this from JavaScript?

Hm.. this might be automatable with AutoHotkey. I'll look into it a bit later if no one else has. – Bob Feb 16 '13 at 11:35
If it hasn't already happened, I'm sure someone will come up with an add-on to call this function, complete with customizable hotkey support. – Karan Feb 16 '13 at 16:35
