Title: Firefox 27 and nss 3.15.4

xulrunner wanted the newer version of nss

I made firefox's preConfigure cd to a subdirectory, because otherwise I saw the following message:

***
* Building directly in the main source directory is not allowed.
*
* To build, you must run configure from a separate directory
* (referred to as an object directory).
*
* If you are building with a mozconfig, you will need to change your
* mozconfig to point to a different object directory.
