Delta Airlines doesn't support Firefox?

zoogies writes: So, I've got a flight in the morning and I need to print out my boarding pass. It's Delta. I go, check in, and go to print. There's a large button that says "Print Boarding Pass Now!" I click it...nothing happens. The status bar reads javascript:printPasses(). I try this in Internet Explorer and it says I'm ineligible to print passes now.

So...I guess I'm wondering, is this an isolated incident, or does Delta just not support Firefox? How can they not offer support? I certainly didn't notice them saying that on their website. It seems rather irresponsible...I'm sure this won't prevent me from flying or anything, but having "Print Boarding Pass" just not work in a widely used browser seems like it'd be a rather huge issue, right?
