Comment 48 for bug 968759

Unfortunately Adobe will change the version of their extended support release from 10.3 -> 11.7 (on Windows and Mac). From http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html :

"Beginning July 9th, 2013, we will be updating the version of our "extended support release" from Flash Player 10.3 to Flash Player 11.7 for Mac and Windows. To continue to stay current with all available security updates, install the 11.7 extended support release. Or, update to the most recent available release (11.8, etc.) "

This probably means, that the linux 10.3 branch isn't maintained any longer either. In that case, the proposed solution from my previous post is not valid anymore.
