Look, I think firefox is an excellent product. 1.0.7 is loaded on my machine and I use it about 30% of the time. I'm just sick of the smug anti-windows crowd crowing on how much MS sucks at security when the products they run are every bit as bad. The only difference is that no one seems to bother to write expoits for the sub 5% marketshare space.
no, they aren't as bad.
1. With Firefox et al, peer review through open source makes it more secure than proprietary closed code bases.
2. Windows is usually run in the equivalent of root, which isn't as secure
3. Windows is built with an enormous amount of services and code running that nobody seems to understand. Linux is all open and people understand what goes on in it.
