Anyone notice that the 'download button' for Flash Player doesn't show up in Firefox's browser although it does in Internet Explorer? I'm not sure if the issue is confined to my computer or others are also experiencing this strange issue. Try the link with the two different browsers and see. http://get2.adobe.com/flashplayer/
Moving this discussion to the Installing Flash Player forum.
Use the offline installers from helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html#main-pars _header until the issue is fixed.
