I have tried all of the steps outlined at http://helpx.adobe.com/flash-player.html but I am still getting notifications to update to latest version even though http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html reports I have latest version installed?
Using latest verion of FireFox 19.0.2 as primary browser, IE9 as secondary.
What versions do you see installed in the Flash Player Settings Manager (Control Panel)?
Both ActiveX and plugin?
Can you post a screenshot of such a notification?
