As per the latest stats Firefox has a significant market share of 35.6%. And still, I see web pages that say, switch to IE for better results.
I was tempted to think that the application will work fine in Firefox. I may switch only if I want the page to look better. Nope. The message is typical marketing spin on saying that we don't support any other browser than IE. The app won't work on Firefox. The app hung up in that page after entering the details. The same page works fine in IE though.
The very moment, I thought I never have to go back to IE, I find a web site like this. The story goes on.
