FireFox on mozilla-russia.org - validation of the installation file for the Windows platform

Question

Mozilla

Hello %username%!
Procedure:

1. I go to mozilla-russia.org/
2. I click on the link "Firefox for other systems" - I get to mozilla-russia.org/products/firefox/
3. In the “Russian assemblies” section, I click on Windows, i.e. on the link download.mozilla.org/?product=firefox-21.0&os=win&lang=ru
4. I'm waiting for it to load
5. Then I calculate the hash
   

   $ cd ~/Загрузки
   $ md5sum -b "Firefox Setup 21.0.exe"
   626ecba908cb0beb3be1025ce53366f1 *Firefox Setup 21.0.exe
   

6. I climb on Google, I drive in 626ecba908cb0beb3be1025ce53366f1, I get
   

   No results were found for 626ecba908cb0beb3be1025ce53366f1.

   
   
7. While it is written on the CITForum.ru RSS feed that the news about the release of FF21 was received on 15-MAY-2013 04:29 MSK.
   Usually, such a validation method rolls, i.e. by the time of release, the binary has time to spread to exchangers, on which the MD5 hash has already been calculated. Has something gone wrong now? I downloaded it twice, for reliability - the hash is the same. On Yandex, the hash is also not searched.
   
8. CHADNT? Is there a more sane way to check the validity of the distribution file downloaded from the above resource?
