It is important to keep add-ons up to date. Updates are made available by the add-on developers to correct security issues (and to add new features).

You can turn off checking for add-on updates at your own peril: Tools > Options > Advanced, Update tab, un-check "Add-ons".

Why are you using such an old version of Firefox? You are 10 updates behind. See:

Duplicate plugins

You have 2 Adobe Reader (PDF) plugins listed in the information that was included with your original question (click "More system info..." to the right of your original question):

  • Adobe PDF Plug-In For Firefox and Netscape
  • Adobe PDF Plug-In For Firefox and Netscape "9.4.1"

The first one is probably a very old version and is probably located in your C:\Program Files\Mozilla Firefox\plugins folder. If you see a file named nppdf32.dll in that folder, either rename, move to another location, or delete that file.

See: http://kb.mozillazine.org/Issues_related_to_plugins#Disabling_plugins_found_in_the_plugins_folder

Other issues that need your attention.

The information submitted with your question indicates that you have out of date plugins with known security and stability issues that should be updated. To see the plugins submitted with your question, click "More system details..." to the right of your original question post.

  1. Check your plugin versions: http://www.mozilla.com/en-US/plugincheck/
    • Note: plugin check page does not have information on all plugin versions
  2. Update Adobe Reader (PDF plugin):
    • From within your existing Adobe Reader (if you have it already installed):
      • Open the Adobe Reader program from your Programs list
      • Click Help > Check for Updates
      • Follow the prompts for updating
      • If this method works for you, skip the "Download complete installer" section below and proceed to "After the installation" below
    • Download complete installer (if you do NOT have Adobe Reader installed):
      • Use the links below to avoid getting the troublesome "getplus" Adobe Download Manager and other "extras" you may not want
      • Use Firefox to download and SAVE the installer to your hard drive from the appropriate link below
      • Click "Save to File"; save to your Desktop (so you can find it)
      • After download completes, close Firefox
      • Click the installer you just downloaded and allow the install to continue
        • Note: Vista and Win7 users may need to right-click the installer and choose "Run as Administrator"
      • Download link: ftp://ftp.adobe.com/pub/adobe/reader/
        • Choose your OS
        • Choose the latest #.x version (example 9.x, for version 9)
        • Choose the highest number version listed
          • NOTE: 10.x is the new Adobe Reader X (Windows and Mac only as of this posting)
        • Choose your language
        • Download the file
        • Windows: choose the .exe file; Mac: choose the .dmg file
    • Using either of the links below will force you to install the "getPlus" Adobe Download Manager. Also be sure to uncheck the McAfee Scanner if you do not want the link forcibly installed on your desktop
    • After the installation, start Firefox and check your version again.
  3. Update the Java plugin to the latest version. (Firefox 3.6 versions require at least Java version 1.6.0_10; you have version 1.6.0_07; current version is 1.6.0_22)
