I was trying to pay my Verizon Wireless bill a few weeks ago and it kept having problems. I checked the credit card number, the expiration date, and every other field, but it was still not working. Finally I got fed up enough to call tech support rather than risk being locked out or something. So I gave them a call and the lady says to me, “oh, you’re using Firefox aren’t you?” “Yes I am” (because I don’t like viruses and other M$ exploits taking over my computer) “Oh well, I’m sorry, but you can’t use that browser here to pay your bills.” “What?” “Oh, don’t worry, our engineers are working on it.”
