Hello all! I have observed a problem when I try to print a webpage in Firefox v28 using the Acrobat PDF Printer (Acrobat Pro 9.5.5) installed in a Virtual Machine (VMware View 5.2) with Windows 7 64 bits. The printing dialog hangs (no response) after the "Save as" pdf dialog. Then I have to force Firefox to close, and afterward a Acrobat PDF conversion dialogs appears with the progress bar stopped at the middle. I also have to close this afterwards. The others programs (Office, IE, Notepad...) are able to print through the PDF printer without problems. The problem appeared after the automatic update to Firefox v28, since when I downgrade to Firefox v26 the problem disappears. I checked a similar configuration in a physical computer (W7 64 bits, Acrobat Pro 9.5.5, Firefox v28), and everything runs good, so I think it is a change that happened in Firefox v28 that has some problem with the VM configuration. I also have tried to change the Firefox profile, reset Firefox and reset the printing settings and reinstall Acrobat. No luck. I would like to know if somebody know some change in Firefox v28 related with the printing or related to some service or update that can have some problem in the virtual machine. Any help is welcome! Thanks!
