Primary Internet Web Browser Plug-in List

Adobe Plug-ins

Adobe PDFViewer
The Adobe PDFViewer web browser plug-in is installed by Acrobat v8 (or later) Reader or Professional version and works with Apple's Safari. NOTE: There are potential problems with some versions of the Adobe PDFViewer if you are running Safari in Rosetta or 64 bit mode so you might want to disable the PDF Viewer. Or you can disable it for security reasons (if you trust Apple to keep their PDF viewing software more up-to-date than Adobe).
  • There is no point in deleting the Adobe PDFViewer plug-in from the Macintosh HD > Library > Internet Plug-Ins folder as the "self-repair" feature of Acrobat / Reader will just reinstall it!
  • To disable the Adobe PDFViewer plug-in start Acrobat or Adobe Reader, go to Preferences > Internet and untick the "Display PDF in Browser" option. This will cause any PDF to display inside the Safari window using its native PDF viewer but note that Apple's PDF Viewer may not support all Adobe PDF workflow features such as Collaboration or some of the more complex Forms.
Adobe Flash Player
SECURITY WARNING: Adobe Flash Player is no longer supported on Intel Macs running Mac OS X 10.4/10.5. If you still use Mac OS X 10.4/10.5 you are now strongly recommended to remove Flash completely
SECURITY WARNING: Adobe Flash Player is no longer supported on Apple PowerPC computers. If you still use a PowerPC computer for browsing the internet you are now strongly recommended to disable flash or better still remove Flash completely especially as Flash vulnerabilities are now being actively exploited on the internet - ClickToFlash for Safari / Flashblock for Firefox or Seamonkey.
WARNING: As of 24/06/2013 Adobe are being naughty by adding the option of downloading a "Lightroom" demo with the Flash Player plug-in. Do not download this software unless you really want it – make sure the box is UNTICKED before proceeding with the download!
  • Check for an update now:
    • If you are running Flash v10.3.181.14 or later go to Apple menu > System Preferences > Flash Player > Advanced tab and click the "Check Now" button.
    • If you are not running Flash v10.3.181.14 or later there is no automated update facility for Flash but you can check if you are running an outdated version by going to Mozilla Plug-in Checker.
  • Turn on Automatic Updates:
    • If you are running Flash v11.3.300.257 or later go to Apple menu > System Preferences > Flash Player > Advanced tab and make sure either the "Allow Adobe to install updates (recommended)" or "Notify me to install updates" option is on.
    • If you are running Flash v10.3.181.14 to v11.2.202.235 or later go to Apple menu > System Preferences > Flash Player > Advanced tab and make sure the "Check for updates automatically (recommended)" option is on.
    • If you are not running Flash v10.3.181.14 or later there is no way to turn on automatic updates.
  • Download the latest version/updates manually from the Adobe Flash Player web site.
Adobe Shockwave Player
SECURITY WARNING: Adobe Shockwave Player 12.x or later no longer supports Mac OS X 10.4/10.5. If you still use 10.4/10.5 you are now strongly recommended to remove Shockwave completely
SECURITY WARNING: Adobe Shockwave Player is no longer supported on Apple PowerPC computers. If you still use a PowerPC computer for browsing the internet you are now strongly recommended to remove Shockwave completely especially as Shockwave vulnerabilities are now being actively exploited on the internet.
