I am not a gmail(web interface) user, so haven't used it but congrats on the launch! I like how your landing page is so simple and small. And the domain is amazing!

I just wanted to point out, I love my Firefox but the gradient animation is so bad on Firefox!

At first I thought oh cool bg animation, checked the dev tools to know what it is only to realize this shouldn't be a color band animation as I see it!

Chromium based browser have it so subtle, that I barely notice that animation, I question does it even exist on it(it does!)?
