Sounds like the guy is cherry-picking some of his statistics to me. He seems to compare IE6&7 to Firefox 1x & 2 interchangeably into whatever combination gets him that results he's fishing for.

Firefox is no panacea- but I've been far happier, far more secure, and have gotten far less spyware (pretty much none) since I moved to Firefox w/NoScript & AdBlock. I keep meaning to check out Opera, but it's tough to leave Firefox- when it aint broke, don't fix it.

Does anyone know if Opera has any widgets that parallel NoScript and AdBlock?
