Why is my Java plugin being hidden?
I have Firefox 10.0.5ESR and had Java 6 update 31 and all was well. I've updated to update 33 (we need to stay on the 6 line for the time being for corporate apps) but Firefox doesn't like update 33. It's not visible in about:plugins or in the Addons page. If you go to the plugin check page you get
"Missing JAVA?
For your safety, Firefox has disabled your outdated version of Java. Please upgrade to the latest version."
which is odd because it wasn't saying that about update 31! (The troubleshooting info below says 10.0.4 because I tried downgrading to that to see if it would help - it didn't!)

The usual places to scan for plugins are in these registry keys:
HKCU\Software\MozillaPlugins\plugin-id HKLM\Software\MozillaPlugins\plugin-id HKLM\SOFTWARE\Wow6432Node\MozillaPlugins\plugin-id

Hi MrSoapsud, try delete pluginreg.dat in Profile folder and check it again.

Done that, several times - didn't help... Need to identify what it is that's triggering the box on the plugincheck page (among other things)
Make sure that you've installed the 332 bit version of Java. Firefox won't work with a 64 bit version.
See Java Platform > Java 6U33 (Download JRE)

Yes - should have mentioned - it is the 32 bit version I'm playing with...
Do you see the Java plugin on the about:addons page (Tools > Add-ons > Plugins) as being enabled?
If not then you may have a problem with missing registry keys that Firefox uses to scan for a plugin like Java.
Try to uninstall Java with the JavRa program and reinstall Java.
Make sure that you run the Java installer as Administrator if you keep having problems.
No - it's not visible at all on the plugin page.
Will take a look at the registry side of things - do you know specifically where FF looks?
JavaRa didn't help but clearing out some reg keys under HKLM/Software/Javasoft and /MozillaPlugins has done the trick. Many thanks.

Turned out the real problem was that the uninstaller for either 6u29 or 6u30 was re-writing "HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins\@@java.com/JavaPlugin/Path" to the old new_plugin version even though the current version installed needed the path with plugin2 in it! Taken a long time to work that out - thanks Oracle!!
