"Lean mean browsing machine!"4.0 starson by Anysia
Pros: Great interface, security, clean browsing
Cons: Not all current extensions work, but that should change after Beta
Summary: Same great browser, with new features. I have to respectfully disagree with CNET's reviewer, as it appears it is IE7 that has been playing catch up with FireFox, not the other way around.
Many of the current Extensions I have installed do work, but a few notable ones, that I rely on don't at this time. That is about the only CON I see.
I really like the webform spell checker, and the ability to add words to it.
I don't know why some people have a problem with FireFox being a 'memory hog', but it could have something to do with how many tabbed windows, or extensions running. All I can state is that I only have 50 to 70 megs of usage when it's running, no matter how many windows.
It's a sweet browser, and I am really looking forward to the final release version.
