First impressions, much faster, smaller memory foot print, websites look much crisper. Overall A+ and as in comparison to IE there is simply no comparison.
Although Firefox 3 is still a beta, they have really hit a home run here. As of today I will use the beta version. Drawback to doing this is that most of my plugins don’t work. But the lower memory footprint really convinces me this will be the browser to use for a very long time. PcWorld/Reuters
