Browser Bothers

Why don't people realize that there are browsers other than Internet Explorer?

I've been trying to book tickets for my Goa trip for the last 2 days on Firefox on my Mac. First of all the site (Air Deccan) was extremely slow. When I finally entered the details and hit "Next", it took forever and eventually timed out.

I kept thinking it was due to the traffic on the site. Then I decided to try my mom's laptop which has Windows XP (ugghh!).

Surprisingly, everything worked like a charm. The pages loaded up fast and the credit card processing went through like a breeze.

Now, I'm sure that has nothing to do with the operating system but more to do with the browser the site has been optimized for!
