Using GreD to get the path to libnss3.dylib is broken since Firefox 35

SSL Observatory WARN: Failed to initialize NSS component:Error: couldn't open library /Applications/Firefox.app/Contents/Resources/libnss3.dylib

And this is correct as the lib is in /Applications/Firefox.app/Contents/MacOS/. Using GreD is not working anymore:

Note: On Mac OS X, up through Firefox 34 this is the Contents/MacOS directory within the application's bundle. Starting with Firefox 35, this is Contents/Resources. This change was required in order to comply with Apple's new Gatekeeper v2 rules; without this change, Firefox would not work on any Mac OS X newer than 10.9.4.
