For info Acrobat Pro 9.4 is now available, see http://www.adobe.com/support/security/bulletins/apsb10-21.html Check your settings as shown in the [[opening PDF files within Firefox]] article.

You also have other out-of-date plugins. You need to update your plugins. It is important to keep them updated due to continuing security fixes and improvements in those plug-ins: * Adobe Shockwave for Director Netscape plug-in, version 10.2 * Next Generation Java Plug-in 1.6.0_20 for Mozilla browsers #'''Check your plugin versions''': http://www.mozilla.com/en-US/plugincheck/ #*'''Note: plugin check page does not have information on all plugin versions''' #'''Update Shockwave for Director''' #*NOTE: this is not the same as Shockwave Flash; this installs the Shockwave Player. #*Use Firefox to download and SAVE the installer to your hard drive from the link in the article below (Desktop is a good place so you can find it). #*When the download is complete, exit Firefox (File > Exit) #*locate and double-click in the installer you just downloaded, let the install complete. #*Restart Firefox and check your plugins again. #*'''<u>Download link and more information</u>''': http://support.mozilla.com/en-US/kb/Using+the+Shockwave+plugin+with+Firefox #'''Update Java:''' #* Download and update instructions: https://support.mozilla.com/en-US/kb/Using+the+Java+plugin+with+Firefox #* Removing old versions (if needed): http://www.java.com/en/download/faq/remove_olderversions.xml #* After the installation, start Firefox and check your version again.
