PDF documents no longer open in windows app (Adobe) after update

Hi. This is more of a bug report than a question, but after new update our company got a big problem: we print from firefox, but we had it set up so as we open the PDF document it would open directly into Adobe Reader (and then print). After update this is no longer available, altough the settings say clearly "open with Adobe/windows application". Is there a possible solution? Thanks for the answer
