有冇人見過一副有關Browsers既市佔率既timeline

Yes, and it is done by StatCounter Global Stats in 2010.

From the diagram we know the world's top 5 browsers ( in order ) is Internet Explorer, Firefox, Chrome, Safari and Opera.

From the button below, you can select Region or even Country in return to investigate their popularity in different areas, and not Global one.

Hope I can help you.
