I have Adobe Flash Plugin v11.2r202 in Firefox 11.0, on Kubuntu 11.10 64-bit. Flash works flawless on Youtube. However, certain websites claim that I need a more recent version of Flash Player. That is, of course, a wrong assumption. Because I have the latest version installed. Also, I tried Firefox add-on "flash aid". It didn't help. For example, on this website: http://htwins.net/scale2/ It says "You need a more recent version of Adobe Flash Player." Whereas in Chromium or Opera, it works. What is the problem there?
