Orange (Hutch) does not work with Firefox?

I tried to check my details on the Orange Website (Orange in Mumbai, Hutch in other parts of India) but it failed to login through Gecko browsers like Firefox. Not surprisingly, it works on Internet Explorer.

Their new layout is cleaner and nicer but fails to work across browsers. The designers must have decided to do away with browsers to stick to their design. If that is their idea, that sucks!
