Firefox 11 Not Reporting Correct Version of Flash v.

Today (April 14, 2012) I installed the new Adobe Flash v. on four computers (several Mac and several PC/Windows).


Eveything went fine except that Firefox does not seem to have the new Flash on any of the Windows PC's (it worked fine on Mac). That is, when I go to the Adobe test page (, it is reporting that Firefox is using the immediately prior version However, all other Windows browsers (e.g., Opera, IE, etc.) all report the correct version on that test page.


And I checked Windows Programs and Updates and it shows version installed.


So, why is Firefox 11 showing the old version? Anyone have any ideas and hopefully a fix?


Adobe, you should fix this.

    Reboot your machine!


    The new version shows in IE straight away. Strangely, if you check your installed add-ons in Firefox immediately after installing a new version, it shows both the old and new versions. A reboot removes the old version, leaving the newest one to take precedence!


    Exactly the same thing happened to me. It even showed the latest version in 'uninstall programs', so I knew it was properly installed and a reboot was probably required.

    I didn't need to reboot my computer, but I see in the FlashInstall.log file that the ActiveX and the plugin did not update at the same time.  It is possible that the plugin waited with the update until I closed Firefox?
