After installing Java (v.1.7.0_17) via the i386 RPM from Oracle and moving the file into the .mozilla/plugins directory, Firefox does not detect the plugin. From what I have read this should work, but about:config and about:plugins say nothing about Java. Is there something I'm missing?

EDIT: Looking in pluginreg.dat the file is listed as [INVALID]

Your life dude.... it's not fun. Your just like me even though something should work the computer decides it hates me and doesn't do it. – Griffin Mar 8 '13 at 3:00
Not that relevant I guess but I might give you an idea: on Windows mozilla puts up a key in HKLocalMachine specific to the java plugin called MozillaPlugins, down to the exact path of that npjp2.dll. After a java update the msi installer messed that up, I got it working on Firefox, but Chrome is still affected. What the installer did was to mess up the path, from bin\plugin2\npjp2.dll to bin\MsiExec\npjp2.dll, which doesn't even exist as a path. Try finding the exact config where is defined, if it has a similar setting like in Win. [INVALID] is an indication of that. – JasonXA May 22 '13 at 18:36

Okay. While I did not know the answer right off the bat I did manage to find something that should apply. While this was from fedora-14 it should still apply today. Try following the steps here.

Edit: If that doesn't work I found another one that is for Fedora 17 here.

EasyLife didn't work. Firefox still doesn't recognize the plugin. – Nate Koppenhaver Mar 8 '13 at 19:00
