What about Opera?

Firefox doesn’t work on my PC anymore. (I wrote a comment about it.) I removed all recently-installed programs incase they were the source of the problem. I did a virus scan and a spyware scan. I removed Firefox, defragged my hard drive, and reinstalled Firefox. It’s still not working, and I’m not interested in wasting anymore time trying to fix it (unless it’s an easy fix I’ve overlooked). So I’m thinking about switching to Opera, which I know nothing about.

Anyone ever use Opera?
