Just noticed that there've already been interesting discussions about Uzbl on HN:

What I wonder the most about is why they don't try to bring a command line interface to firefox, kind of like how you can call safari and its content from applescript.

I think firefox can already be used with keyboard shortcuts only and they have a hard time getting their browser to be half as fast.

What configurability is concerned, I think that mozillas choice of saving all the user configs etc in a sqlite database is easy enough to access by script.

Still interesting and probably good fun to fool around with!
