It's preliminary..

It's preliminary, but Google's Chrome browser has some neat ideas. Sadly I just think of them as things I'd like to see Firefox pick up.

Tearing tabs off into new windows? I've been waiting for that.

Smart new tabs that suggest based on your browsing habits? A nice extension of the Super Bar or whatever idea that Firefox has.

Maximizing vertical space? They could take it farther(further?) but it's more important to provide for this in today's freaking widescreen environment that cuts your vertical space down.
