Mozilla Firefox 37.0 – Final

Thanks Petr, but only from FTP link as yet, and e.g. "All Systems and Languages" serving v36.0.4 still, and Release Notes still showing Beta,
 
    " Mozilla will release new versions of the Firefox web browser for all supported channels later today.....
Firefox 37 is already available on Mozilla's public FTP server. It is usually not a good idea to download it from there directly as last minute changes may make a different build the release build.
While this does not happen often, it did happen in the past."
