Question

I keep getting a class not found error when I try to load a java applet on firefox

I’ve tried multiple things to fix.

Cleared the Java temp files

Deleted all installations of Java and reinstalled the latest.

However even the java test page fails to load 🙁

Heres the error:

heres the dump from the test page
