Mozilla recommends update of Adobe plug in for Reader. Mozilla won't allow viewing files because plugin is out of date, When trying to update to, Mozilla blocks the update and says it is "out of date." This is being installed on a WIndows 7 desktop.

hello, adobe has released a critical patch for a vulnerability in its flash plugin, which is reportedly already exploited in the wild. therefore firefox will block insecure versions from running by default on websites for your protection.

please update to Adobe Flash Player version as soon as possible, which you can download from (use the windows-exe for plugin-based browsers).

Hello Everyone,

I used the link from Philipp and downloaded the Windows Flash Player for Plugin-based browsers. After closing FF to complete the installation I started FF to find that Flash Player is installed and active in the list of plugins.

Hi johnmyself, cor-el has covered Flash. For the other two:

  • Adobe ReaderAdobe PDF Plug-In For Firefox and Netscape - because Adobe doesn't support Reader XI on Vista, you're stuck with the Reader X series and corresponding plugin 10. Mozilla's plugin check site only considered the current plugin 11 series to be up-to-date, so you'll have to rely on Adobe to keep you on the latest Reader X and plugin 10. You can use Help > Check for Updates in Adobe Reader X to watch for updates.
  • Adobe Flash PlayerRealNetworks(tm) RealDownloader PepperFlashVideoShim Plug-In - this is something supplied by RealDownloader and most likely would be updated when you update that software.

as to the adobe reader - that installer says that I have a more recent version than the one available already installed.

oh well
