Citrix Java Applet does not load on any other browser except internet explorer

I have a Citrix MetaFrame XP Server - Feature Release 3. A couple years ago I setup a web site so users that didn't have an ICA Client could connect using Java. It worked fine for Windows and Macintosh Machines alike.

Fast forward to today and now the java applet only works on windows machines with internet explorer (doesn't work on Macs at all or Windows with Firefox or any other browser except IE).

When the page is loaded, firefox displays a box with a red X in the upper left corner. The status bar says: "Applet.com.citrix.JICA notinited" then "Loading Java Applet Failed..."

Here's the Java Console Log from Firefox:

I've searched all over Citrix's support site and the interweb and nothing comes up that is quite like this. Does anyone have any suggestions?Start Free Trial
