Have used Firefox for years. The tabbed browsing idea was years ahead of IE.
I also find it easier to use lots of the other browser features. IT seems to be much more user-friendly than IE.
I don't know if it's still the case, but it always used to be said that most of the viruses were written to be effective only on PCs running IE. I would imagine that the little scrotes have "cross-platform" mayhem built into their work these days.
