I have been using firefox for my web browser for years, and run some business applications through the internet, like shipping via UPS, and Charging credit cards. When having to print labels or receipts there was never an issue, until today. While trying to ship our largest order yet via UPS, the labels would not print, a label i presented in a pop up and should print. However, nothing from the firefox windows will print today. WHY? Stephen PS, the shipment was the largest one to date by the way, and the most important, everything went smoothly up until Firefox.... What a drag.
