Re: Which Browser should I use?
Firefox is the king of the roost these days for everyone that knows what they're doing, and not without good reason. It's a fast, standards compliant, fully functional and very extensive browser that's held up to all sorts of security attacks very well.
Some recommend opera yes, but I can't really see why. The only argument I ever hear is "ooh but it passes acid3!" Great. But in the grand scheme of things, that really doesn't show much at all. To me it's always seemed like a browser on the side for people that don't like using what everyone else is using for no good reason. There's nothing wrong with it per se, but I can't see its advantages over firefox in the slightest.
Chrome is a great up and coming browser, and for what it is I love it. My only qualm is that there's not many plugins for it due to its young age, so I'm sticking with firefox for now. In the future though, who knows... :-)
