1. Firefox is free and open source. If it's free, it must not be that great.

2. Firefox is more secure that Internet Explorer. But that isn't important...we all trust Microsoft to keep us safe.

3. Firefox has too many free add-ons. Who has time to browse through so many?

4. Firefox is faster than Internet Explorer. You won't have time to take care of those odd jobs around the house or office while a page loads.

5. Firefox is the browser of choice for almost all web developers, web designers, and webmasters. But what do those guys know?

6. Firefox has a cleaner, more customizable interface. So what?

7. If you start using Firefox, you may never go back to Internet Explorer. So best not risk it!
