  firefox sets LD_LIBRARY_PATH which breaks the icedtea6-plugin

Bug description:
  Binary package hint: firefox

  starting with openjdk/icedtea-1.7, a NSS based security provider is
  supported by icedtea.

  The firefox start script in MOZILLA_FIVE_HOME sets LD_LIBRARY_PATH to
  include MOZILLA_FIVE_HOME and a number of subdirectories of
  MOZILLA_FIVE_HOME. The current NSS provider code seems to honor
  LD_LIBRARY_PATH, and loads the libnss3.so provided by the browser.

  Caused by: java.io.IOException: An incompatible version of NSS is already loaded, 3.7 or later required
          at sun.security.pkcs11.Secmod.isInitialized(Secmod.java:130)
          at sun.security.pkcs11.SunPKCS11.<init>(SunPKCS11.java:168)

  (wondering why the nss version shipped with firefox 3.6.3 identifies
  itself as 3.7).

  However the openjdk build is configured for the nss version configured
  at build time, and you can run it with more than one browser, so it
  makes sense to use the libnss version which was detected at openjdk
  build time.

  My current solution/workaround is to pass a modified LD_LIBRARY_PATH
  to the subprocess such that the libnss3.so which was configured at
  build time is always used.

  The setting of LD_LIBRARY_PATH in the run-mozilla.sh start script may
  be convenient, but it does break plugins which are built to be
  independent of the browser used.

  Things to do on the browser side:

   - why does firefox use it's own outdated libnss copy, and doesn't use the system nss3?
   - why does the nss shipped with firefox identifies itself with 3.7?
   - the firefox startup script should not set LD_LIBRARY_PATH, but search itself for libs
     in known places.

  for a proposed workaround for the icedtea6-plugin to work with this
  broken plugin, see
