FIrefox or Opera?

Many people know about Firefox, but just a few know about Opera.

I have been using Opera for the last 2 years and I am very happy with it. Opera offers great features that Firefox locks. I am not saying that Firefox is not good but that it doesnt offer the same features Opera offers.

When it comes to choosing which browser to use, people often go with the most popular one, without knowing that there are more than just one browser available.

Which one do you use? or, Are you still using IE?

Isn't it time to upgrade?
