There was a time when I never knew there could be an alternative to Internet Explorer. Then for a long long time, Netscape Navigator was the only known Browser competing with IE.
Netscape, however, could not stand the popularity of IE and could not directly compete with Microsoft. So, it started supporting a fast growing browser company called Mozilla. Mozilla had a browser, a eMail application and a Chat [IRC] application. Mozilla had a great luck, when Google also started supporting Mozilla for the production of the Latest, and my favourite browser - Mozilla Firefox.
Firefox is a classic straight forward browser, and Open-source. Firefox is not fast, not user-friendly as Opera is. But it is primitive and a long time use with it will make you love Firefox.
With Firefox (25 million downloads, so far) and Opera alone in the competition, IE is no where in the picture. Eventhough 70 % of web-users use Internet Explorer browser, this picture is likely to change.
So, what browser are you using, I would reccomend Firefox.
