"offers many advantages over Internet Explorer, such as the ability to block pop-up windows"

Guys, atleast write the correct description, out of all the features what you find worth mentioning is "ability to block pop-up windows" (faint)

This is an RC, not the final. Check your sources.

This version of Firefox isn't ready yet! Release candidates are not official releases and not meant for general use. If you're looking for Firefox 3 Beta 3, we recommend you watch Mozilla Developer News for the official release announcement.

Actual link is correct, its final beta 3 not just a nightly build.

Damn, its a bloody trap, judging by the link u think its final, but it really is just an rc.

Is there an estimated date for the final version yet? I'm looking forward to this :D
