Cool Firefox2 feature.

Ok, I know I'm supposed to represent ubergeekdom around here but sometimes I'm slow. However if you've never noticed this, you'll appreciate it.

If you select Google as your search engine in the FF search bar and type in, how many feet in a mile, you see the suggestions menu appear under it. The answer will be in the menu. It does this for just about any conversion. Even if you ask for "how many meters in a mile"

A cool and very well thought out feature.
