I didn't really know much about Fire Fox 3 and when it was going to be released even when I had the beta version on my computer, but after reading this article from PC World I'm hyped over these new features. Hopefully everything will go smoothly when it's released.

What I'm most excited for:
Better Performance - I"ll admit when I'm on my shitty laptop it experiences some crashes due to too many applications running + FireFox/Add-ons.
Better Bookmarks - I have 6 sites that are RSS'd and I'm a bookmark addict, I stumble upon an interesting page - I bookmark it. This feature will enhance and organize your bookmarks than before.
I really can't wait to see how awesome FF will get.
