I’ve been getting plugged into the world of Firefox, and man, it rocks. I really like it, and I especially like that there’s a huge library of different extensions that can make Firefox just about jump through flaming hoops. As I keep adding more and more, however, I’m starting to worry about whether it’s possible that some of these extensions are actually spyware or viruses. Is that even possible? And if so, how do I avoid being suckered?
