Actually, I agree.
I was running the Chrome dev builds. I switched back to Firefox (well, to the 4.0 betas). I'm on an old - dying - c2d Macbook. Firefox is indeed faster.
Apart from speed: I really like Chromes UI but it's hard for me to ignore the fact that Firefoxs add-ons are ahead at this point.
I keep trying other browsers and I'll gladly change again if I find something better for me.
Well, these are my experiences and I'm no fanboy of any browser or OS.
I noticed you got some comments from people who claim you're lying, a Firefox dev and so on.
Proves there's a war out there but this war is being fought between a couple of companies - it's always tragic to see people taking sides, no matter if it's Mac/Win, Xbox/PS, Firefox/Chrome. Use what's best for you and stop wasting your time hating for no reason.
