From the readme file in ftp://ftp.mozilla.org/pub/mozilla/releases/m8/ : The fullcircle (or fcircle for mac) packages include third party
software, to aid the mozilla developers in the tracking of crashing bugs; the windows fullcircle package does not contain many of the test executables contained in mozilla-win32-M8.zip.
The third party code is *not* open source, but most of the build is the same as mozilla-win32-M8.zip.
