I am a fullfletched firefox user. Internet Explorer is too slow. Chrome is disturbing somehow.
I didn't try the rest till now but Firefox works perfectly fine.
(Am I the only one who is disturbed by the advertisments on the bottom of the site while tiping a comment?)
Chrome is alright, but it's Google so you know they're just datamining the hell out of you. I like it, but I'm a security buff so I use Firefox(That and my computer has a ton of horsepower)
