"It's a good basic browser that works smoothly."
It is not as prone to hacking and other offensive internet problems as Explorer. It's widely used and accepted for its reliability.
It don't like it as well as Goggle Chrome, but not all programs have accepted Chrome, so I use Firefox as my main Windows/Mac backup browser.
Overall, it's an excellent browser that gets the job done. I'm not a geek, so I can't really criticize it's technical value, but it works for me and I've had no problems with it when I use it.
