I use Firefox 3.0.1 on Pardus 2008.1 (upgraded from 2008) with in Firefox the Java (TM) plug-in 1.6.0_06 and Shockwave Flash plug-in 9.0r124.
The bingo game works fine.
I hear no sound but that happens more often, somtimes the sound is via the sound-on-board of the motherboard (speakers are not connected to that, front headphone sockets are), my speakers are only for output of my seperate soundcard.
But I understand your problem is not about sound but about the applet not opening at all?
Anyway strange that you are unlucky whilst other Pardus users (including me) encounter no problem at all at this issue.
Yes, I have all those loaded and showing in firefox. When you are at the pogo wesite do you log in a member? The reason I am asking is, If I play as a guest, the game works fine, but when I log in as a member the applet does not work. Says applet is not init or applet loaded..which is is not.
