My Java plugin isn't detected in my trunk nightly, on 64-bit Windows 7, and it works fine in Firefox 10 (same machine).

Additional info:

My nightly build is installed in C:\Program Files\Nightly, while Firefox 10 is installed in C:\Program Files (x86)\Mozilla Firefox.

Java is installed in several subdirectories off C:\Program Files (x86)\Java (see screenshot).

Screenshot
You are using a 64bit nightly build while your release build (as all current Windows release builds) is only a 32 bit build. You can see the difference in the UA string: Win64 vs WoW64
I don't know if we currently support using 32bit plugins via a 32bit plugin-container on windows64.
Is java working you change dom.ipc.plugins.java.enabled to true ?

No, that didn't fix it; thanks, though!
Stephen: You may want to download the 64bit Java from here.

Depends on: 595053
Why is this bug related to bug 595053? Oracle provides native 64-bit Java plug-ins.
No longer depends on: 595053

Have you installed 64-bit Java?
