When Internet Explorer 7 had reached three million downloads in the first four days, the news of the Microsoft browser's performance spread at a global level. In this context Firefox 2.0 deserves a similar treatment since it revealed that it is capable of a comparable if not superior performance. In this context, the impact that Firefox 2.0 is making may as well prove superior to that of Internet Explorer 7.

This is the case as Mozilla revealed that Firefox 2.0 was downloaded over two million times just in the first 24 hours. This is equivalent to an estimated 30 downloads each second. Mozilla's Asa Dotzler made a comparison between the success of Firefox 2.0 and that of previous versions.

- Firefox 1.0: 1 million downloads in the first 24 hours.
- Firefox 1.5: 1.5 million downloads in the first 24 hours
- Firefox 2: 2 million (actually slightly more) people using Firefox 2 in the first 24 hours.

When compared to Microsoft's 3 million downloads in the first four days, Firefox 2.0 is clearly more successful. But the situation will be balanced in the favor of Microsoft, as the Redmond Company will begin pushing Internet Explorer 7 via Automatic Updates to all Windows users come November 1.
