From Version 3.02 onwards, Acrobat Reader (now Adobe Reader) has included support for JavaScript. This functionality allows the document creator to include code which executes when the document is read. While JavaScript is designed without direct access to the file system to make it "safe", vulnerabilities have been reported for abuses such as distributing malicious code through Acrobat.[6] On September 13, 2006, David Kierznowski provided sample PDF files illustrating these vulnerabilities. In the most current version of Reader, JavaScript can be disabled using the preferences menu and embedded URLs that are launched are intercepted by a security warning dialog box to either allow or block the website from launching.[7]

After closing Adobe Reader, open your Mozilla application’s installation directory, open the Plugins folder and ensure that the file "nppdf32.dll" is not present. If it is, remove it (or rename "nppdf32.dll" to "Xnppdf32.dll"). Failing to remove or rename this file may cause the browser to hang when attempting to open a PDF file.
