I'm trying to use the Opera Mini Simulator at http://www.opera.com/developer/opera-mini-simulator to test websites on OS X.

In either Chrome's or Firefox's (current, stable/release version of each) add-ons manager, I have the Java Applet Plug-in 14.9.0 installed and enabled.

In Terminal, I can confirm I have Java on my system:

which java --> /usr/bin/java

java -version --> java version "1.6.0_65"

Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)

But when I hit http://www.opera.com/developer/opera-mini-simulator I just see "Missing Plug-in."

Why doesn't this work? I guess it's required to have MicroEMU on the client system as well? Opera's link to MicroEMU goes to a domain-park page; I found it on https://code.google.com/p/microemu/downloads/detail?name=microemulator-2.0.4.zip and put it in my path (/usr/local/bin), but that didn't solve it.
