Under Options, Applications there are multiple entries for the same item. (Adobe Acrobat) . Three show Adobe Acrobat Reader 9.3 and the other shows (ask) or (save file) with no ability to select Acrobat Reader . Is there a way to edit this list to remove the duplicates and the incorrect entry? Adobe installed a very quick update today.

They are all different. Hover your mouse pointer over each of the "Content Type" descriptions and you should see a "tooltip" to see that each has a different description.


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 11.5 (you may need to update)
  • Shockwave Flash 10.1 r53
  • Next Generation Java Plug-in 1.6.0_20 for Mozilla browsers
  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 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.

  3. Update Shockwave Flash
  4. Update Java:
