When I checked for updates to my plug-ins, there were 4 listed as out-of-date that are already installed on my computer. Is there a problem with Firefox recognizing them????

Wondering because I am having problems with not being able to print some stuff from the web or sometimes see media. Plug-ins listed as out-of-date (but that are installed) are Adobe Reader, Quick Time, Java and Flash Player.

If you have problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the DMG file to the desktop
* Firefox 5.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Trash the current Firefox application to do a clean (re-)install
* Install the new version that you have downloaded
Your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks and other personal data.
