Last time I blogged about Firefox (2.x), I was complaining about how much memory it was sucking up. I have read about how many memory leaks were supposed to have been fixed in Firefox 3 but I had to see it to believe it. So after suffering again from low memory while running VMWare and Firefox (whose memory consumption regurarly climbs to 500MB) at the same time, I decided to upgrade and leave Firefox 2.0 for good. Firefox 3.0beta5 is blazingly fast and I have yet to see it use more than 170MB of memory. Thanks to the all the Firefox developers for finally fixing what was probably the biggest problem with Firefox 2.0.
Update: I also installed it on my Linux machine at home and memory usage and performance with many tabs open is far better than Firefox 2.
