Firefox doesn't know that I updated a plug-in.
Firefox was crashing whenever I closed a window. Mozilla Support directed me to the Plugin Check page. It told me to update Java(TN) Platform SE6U37 (among other things). I downloaded jre-7u11-windows-x64.exe. I ran it. The last window said "You have successfully installed Java". I closed everything and restarted windows 7. Then I opened Firefox and followed the same path to the Plugin Check page. It told me to do the same update.

According to this bug on the Oracle site http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8005410 , the problem occurs because their installer did not properly recognize prior Java versions and is compounded by a problem with systems having the JavaFX stand-alone application installed.
So, if you see JavaFX in your list of installed programs (Windows: Control Panel), remove it. It might also be best to remove all Java from your system before installing the new Java.
I would have recommended JavaRa to uninstall all previous Java from your system, but, sadly, it has not been updated since October 2012 and does not include and will not find more recent versions of Java files and/or registry keys. Hopefully the built-in Windows uninstall will remove all of the files and registry entries
Oracle has released Java 7 update 11 to address the vulnerability recently recognized in Java 7 update 10 and some prior versions. Java 6 update 38 was not updated; support for the Java 6 versions ends in February 2013.
Well, Old Fox, I uninstalled Java. I ran the installation program. I went back to the Plugin Check page. It still says to update.
Read this. Firefox is a 32-bit browser; and yes, 32-bit software runs well in a 64-bit environment but the application is installed in a separate Programs folder. The work on a 64-bit version of Firefox was halted for a short time, but is now proceeding on a limited basis and there is no projected release date set.
Did you look for and uninstall JavaFX if present in your Control Panel Programs list?
Please list all Java items in your Add-ons (Extensions and Plugins) along with their version numbers in your reply.

You installed the 64 bit version of Java, you need the 32bit one. http://javadl.sun.com/webapps/download/AutoDL?BundleId=73141
OldFox and Tylerdowner,
Why did Mozilla's Plugin check take me to the wrong software? OK, I'll uninstall and try again.
Voila! thank you tylerdowner. Now I am about one-tenth of the way to solving my problem.
Can I keep this question open as I solve the other ninety percent?
