Windows 7

Firefox 3.6

Adobe Reader 9

Whenever I try to open PDFs in FireFox, I sometimes get a message box with no title and no text, just an "OK" button. I have to refresh the page multiple times to get the PDF to display correctly. Is there a fix for this?

All I can say is to remove Adobe Reader Firefox add-on and reinstall it. – fardjad Jan 31 '11 at 18:46

Yeap, like divided said, uninstall and reinstall the Adobe Reader Firefox add-on. OR, you could try FoxitReader and its add-on, it works better than Adobe Reader, in my opinion.

I uninstalled and reinstalled the firefox addon and I updated adobe reader from 9.3.2 to 9.4.1. This has not fixed the problem. Unfortunately, I can't use another PDF reader since this is in a corporate environment. – divided Feb 1 '11 at 14:39
Hm... Try the following: - Uninstall Firefox, and install its later version (3.6.13, if I'm not mistaken); - Uninstall Acrobat Reader again, and reinstall it. If possible, uninstall all the above using a program like 'Revo Uninstaller', using Full Removal. This was, everything is erased (even registry settings). – gnclmorais Feb 1 '11 at 14:48
