Running 64 bit Firefox 45.0.1 on Windows 7. Installed 64 bit Java jre-8u77-windows-i586 several times, but it doesn't show up on the Plugins list. Yes, I've restarted Firefox. I also tried installing it with Firefox shut down. I made sure the Java installation was going to the Program Files directory vs. Program Files (86) (at this point I think it's gone to both). The Java installer claims it completed successfully. The "Enable Java content In the browser" box on the Java Control Panel is checked. I considered falling back to 32 bit, but java.com only offers the 64 bit version.

I've never had this problem before. What am I doing wrong?

The Win64 Firefox only has 64-bit Flash Player and Silverlight Plugins white listed. If you want to use other Plugins with Firefox on Windows, you need 32-bit Firefox and 32-bit Plugins.
