Firefox 3 Alpha 2 Preview
 

Firefox convinced me that tabbed browsing is the way forward, how will Firefox 3 improve on the experience? This article has some details on the improvements being made:

"While this alpha may have some memory leaks, I am happy to say that it uses much less CPU power than Firefox 2, especially when it’s idle. One of my main gripes with Firefox 2 is that even when it’s in the background doing nothing it still manages to consume 4-5 percent of my processing power, which seems unnecessary. However, when Gran Paradiso is sitting in the background unused its CPU usage drops to zero, which beats even Safari.
