I will add this, when chrome launched its extension shop it was a trojan horse playground. google harvested this.
Here's my opinion; never touching chrome unless i have to, the only positive i see in using chrome is if you limit your use to just c3 on chrome, since every tab is it's own process and that's no good, it's so unstable it would crash my computer trying to compete with opera or second case, firefox, 10-20 tabs in chrome equals 50-100 tabs in opera in terms of performance on ram et cetera. my powerhouse has been happy ever since (and every other computer i've touched, opera > firefox > IE > chrome
I'm probably coming off really pessimistic on these forums, but i have nothing to complain about since i have free access to c3 for a while and can form an opinion from that, though i am wondering how long it will take to get it on the desktop. we all still have c2 anyway, but i will admit after reading about the third party stuff on these forums i am a little concerned.
