Problems updating adobe flash player firefox
To see if the Flash plugin is working and what version is being used, visit one of these pages: If Flash is not installed, this may trigger the Plug-in Finder Service, which you can use to download and install the Flash plugin on Windows (see below).At time of writing, the Plug-in Finder Service is triggered but fails to install the Flash plugin on Linux or Mac OS in Firefox 3 and above (you will need to manually download and install the plugin).For example, for Flash plugin version 184.108.40.206 on Windows, the plugin file name would be "NPSWF32_11_2_202_235.dll".In older Flash versions, for example, plugin version 10.3.183.18 on Windows, the file name would simply be "NPSWF32.dll".
Each must be installed separately, since the Flash plugin installer does not add the Active X control and vice versa.
 An uninstaller can be downloaded from to remove Flash from Mac or Windows systems.
After downloading, make sure you completely exit your Mozilla browser and close all other Internet applications before you run the uninstaller.
You normally don't need to uninstall Flash before updating to the latest version, since the Flash installer automatically removes the older version.
However, you will need to uninstall your current Flash version if you are downgrading from a higher version.
