On http://www.mozilla.org/releases/ under Mozilla 0.9.7 Win32 is the text: talkback enabled Net Installer .exe (21.4 KB) in fact, http://ftp.mozilla.org/pub/mozilla/releases/mozilla0.9.7/mozilla-win32-0.9.7-stub-installer.exe is 214,240 bytes, which is 209.2 1024-byte chunks or 210KB rounding up. Or if you mean kilo (1000), it's 214 kB.
0.9.7 has moved to http://www.mozilla.org/releases/old-releases-0.9.2-1.0rc3.html and the size seems to be (somewhat) correct: 214 KB. Not that anyone cares anymore. Marking this one fixed.
