We use the Adobe plug-in to open and print multiple PDF files from Firefox everyday. Staring last week every time we try and print a PDF file from Firefox it causes Firefox to freeze up, and the only option is to end the program. This is happening on multiple different computers. Two of the computers use Adobe Reader and have the most current version, one of the computers is using Adobe Acrobat version 10.1.15. We have tried all of the basic fixes (i.e. Restarting the computer/browser, starting the browser in safe mode, using the Refresh Firefox option, clearing the cookies and cache, disabling the plug-ins, etc...) nothing seems to be helping. Any insight into how to resolve this problem would be much appreciated.
