Looks like Microsoft Firefox to me.
That "streamlined interface" not only looks awful, but looks like it would be quite clunky. I don't know if it was just the examples shown, but the tabs looked really cramped.
The other thing that caught my attention was that that phishing feature, I wonder how it works (could there be privacy issues there) and I wonder if it can be abused. I'm always wary about software making judgements on content I access.
