Download FP seems to be normal, FP "successfully installed", but partially videos dont work, various websites propose to download FP as if the program is not active. Addon is found active in IE10. When starting the FP-Manager and changing the download options to allow automatical updates, FP is suddenly active, newest installed version is found and displayed on the Adobe-Site, all videos work. Closing the browser and opening it again results in inacticity of FP. The download option in the FP Manager changed again to updates on confirmation. Grrrr....
Also tried to deinstall and install again with deactivated Security Essentials, but no improvement. Grrr....
Chrome works without problems.
FP sucks!
