You appear to be running a recent Minefield (aka trunk/mozilla-central/1.9.3-branch) nightly.  So this bug is a dup of bug 547403.

As of 4/22/2010 the pressure will rise on this issue.  The shipped Firefox
3.6.3 on OS X does not connect properly to Java 1.6_17 for the applet JRE.  If the
applet specifies java 1.5.x it is working.  The workaround at the moment is to
set applets to use java 1.5 only.

Some java 1.6 applets will run with Firefox 3.6.2 if the java preferences are set to use same jre as browser.  The java console may not appear in these cases though so debugging is very difficult.

This was a mistaken test.  The JRE defaulted back to 1.5 in the test.  Firefox 3.6.2 and 3.6.3 hang when the Java Plugin is configured to only load a JRE 1.6_17. in the applet call or java preferences.

This indicates you're using a Minefield nightly.

But from your subsequent comments, and other things you say in comment
#0, apparently this isn't true.

No version of Firefox supports Java 6.0/1.6 on OS X 10.5.X.  Neither
does the Java Embedding Plugin.

Both support Java 6.0/1.6 just fine on OS X 10.6.X.

I was not aware of the OS X 10.5 restriction.  Bit of an issue for me, as the upgrade to 10.6 is not automatic for mac users.  I'm going to have to modify our applets to run in the degraded 1.5 environment for now.

I've been testing with the firefox nightly, 3.6.2 and 3.6.3 as needed on the 10.5 OS X release.  -resolved as duplicate is ok-

Closing old bugs in the Plugins component. We aren't going to track issues in 3rd-party plugins in the Mozilla bug tracker. In addition, support for NPAPI plugins will be removed at the end of this year; for more details see the post at https://blog.mozilla.org/futurereleases/2015/10/08/npapi-plugins-in-firefox/

If there is a serious bug in Firefox, it needs to be filed in the "Core" product, "Plug-Ins" component.
