There is good news for all us Linux users the FDS-TEAM is working on a wine based product called Pipelight it will install the Windows version of Flash 11.9 and Microsoft's Silverlight 5.1 in to a Linux browser FrieFox and Chrome.
They offer repositories for most popular Linux distros, This is the link http://fds-team.de/cms/articles/2013-08/pipelight-using-silverlight-in-Linux-browsers.html It is not perfect yet but it dose work I am using it on OpenSuse and Ubuntu is also supported. They are very helpful if you have problems installing.
The other option is to install Wine from this link http://www.winehq.org/download and then install Fierfox and Windows flash into Wine.
