Despite FireFox having thousands of happy users, I have never been one of them. I am one of those people who will sometimes have more than ten webpages open at any one time and then leave them open on my computer overnight. This meant that FireFox's memory issues always blighted my attempts at using it as my primary browser. So it was with absolute delight that I discovered FireFox 3 (currently Beta 4 with Beta 5 coming soon) has solved all of that.
FireFox 3 Beta 4 is fast and responsive under all conditions. Websites like Google Maps, Digg and IGN that used to be super sluggish under IE and FF2, are now just as fast as any other website. I will even go as far as to say just as fast as a plain text blog.
So if you want to give the beta a go, you can Download A Copy Here. But be warned, I have found that it doesn't work with the new Yahoo Mail (I am using the classic view) and I have had the beta crash twice in the few days I have been using it for no apparent reason. This hasn't been a problem however because it remembers the pages that where open at the time of the crash, but despite all that FF3B4 is my current primary browser over IE7, FF2, Safari and Opera.
