Hello, since around Dec 10, Sirius will Not Stream on my Computer, Please Help, Thanks!

I know a New Version of Firefox was Installed on Dec 05, and a New Version of Flash on Dec 10, it seems that this the time frame when I started having problems with Sirius, I listen to various music channels and talk channels, when I hit Play on the Player, it will Start Playing for 5 to 10 sec and then Stop, I hit Play again and it Plays the Same thing Over Again, for awhile I could restart my puter or Log Out of Sirius and log back in and that would fix the Problem, Now Nothing Works......just to mention, I can use Internet explorer and it Works?, but I do Not Like IE, I want it to Work on Firefox, Hope someone can Help, Thanks!
