Answer 1

I ended up coding a custom solution (Firefox extension) that does this. I think by the time I developed it, the commandline mentioned in enreas wasn't there.

The Firefox extension is CmdShots. It's a good option if you need finer degree of control over the process of taking the screenshot (or you want to do some HTML/JS modifications and image processing).

You can use it and abuse it. I decided to keep it unlicensed, so you are free to play with it as you want.
