Firefox and Chrome ..i generally use...though..heard from many people..OPERA is fast..i am not much focused on it
I use Chrome for all may tasks except....where it fails to display things properly or where it is missing some plugin. In such cases I go back to Firefox. I love chrome because it is FAST.
Firefox is my fave browser, chrome's second . but Firefox is starting to get really slow on me these days... maybe I'm opening too many tabs ^.^
Firefox forever! It's safe, customizable, and have lots of good and useful add-on. I'm not from Firefox company though...
I seem to be switching back and forth between Firefox and Chrome. Firefox is something I got much more use to. It's interface is more intuitive to me after 2+ years of using it, but Chrome seems more reliable and really faster.
