Things like this really make me miss the old Firefox experiment "Ubiquity". It was truly a marvel for the time it was up, and I often wonder why they did discontinue it.
You could search websites, send emails, look at maps and much more (you could build your own commands) without ever actually opening a webpage. It had 200.000 users when they shut it down.
Wouldn't you just be able to fork it and continue as a hobby project of your own? Who knows, maybe you find other enthusiasts and it becomes a real project again. Mozilla licenses are (I believe and could be wrong), quite lenient about these things.
