Do you have Adobe reader installed?
You have a current version of Adobe Reader installed under Plug-ins: Adobe PDF Plug-In For Firefox and Netscape "9.3.2"
Check your settings for .pdf files in Tools > Options > Applications

Other Issues: ~~red:You have installed plug-ins with known security issues. You should update them immediately.~~
Install/Update Adobe Flash Player for Firefox: your ver. 10.0 r45; current ver. 10.1 r53 (important security update 2010-06-10) See: Updating Flash -use Firefox to download and SAVE to your hard drive (save to Desktop for easy access) -exit Firefox (File > Exit) -check to see that Firefox is completely closed (Ctrl+Alt+Del, choose Task Manager, click Processes tab, if "firefox.exe" is on the list, right-click "firefox.exe" and choose End process, close the Task Manager window) -double-click on the Adobe Flash installer you just downloaded to install/update Adobe Flash -when the Flash installation is complete, start Firefox, and test the Flash installation here: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_15507&sliceId=1
- NOTE: On Vista and Windows 7 you may need to run the plugin installer as Administrator by starting the installer via the right-click context menu if you do not get an UAC prompt to ask for permission to continue (i.e nothing seems to happen). See this: http://vistasupport.mvps.org/run_as_administrator.htm
- NOTE for IE: Firefox and most other browsers use a Plugin. IE uses an ActiveX version of Flash. To install/update the IE ActiveX Adobe Flash Player, same instructions as above, except use IE to download the ActiveX Flash installer.
