Unlike others, I am having no problems with crashes on my Intel Core Duo 1.66 Mac Mini. Nor am I experiencing problems closing windows. Speed seems to be improved, and a couple sites that had issues loading are now looking fine. Still some sites that have problems, but this is a step in the right direction. A pretty stable beta imho.

They still need to add a built-in new tab toolbar button option though. It's beyond me why this small feature has not been added as every browser but Safari has it. Would also like to see an option to have links open in a new tab automatically (as Camino and Firefox do).
