It does look a lot like chrome, but it is just a menu selection to drop the tabs back down if you want to. I have a fealing that all of the browsers are heading to tabs on top, so I think I will just get used to it now. I like the beta so far, and it does seem a little faster. Just feels more smooth and polished now. I still need to load all of my plugins to see how they work, but so far I really like it.
Thanks for the heads up! I hadn't seen this yet.
