I use chrome often....maybe if you made it as poll, we could have seen results of what people think here.
Firefox! Fast and there are a lot of add-ons available in the market. I also have IE on my system but barely use it after switching to Firefox!
I do vote for Mozilla Firefox and then Google Chrome. In the first (that means when i am new to the internet i.e. in 2006 i used IE but now i don't find it is efficient anymore).
Fire fox is my browser too, I find it very user friendly. Opera is not bad as well. I like the home page of opera.
