| 	The same thing happens even if I click the plug-in button
| 	before any page is loaded.
|
| 	Any ideas would be nice. - A patch to an already known problem
| 	even better.

Looks like a problem with the Java plugin.  To confirm, try disabling
it, and see if the problem goes away.  If so, try rebuilding java/jdk14.
~ I'm using the Java 1.4 plug-in with Mozilla 1.7.5 without problems, but
I have not tried 1.8 as yet.
