'version' in navigator || (
  navigator.version =
    /(?:(?:OS(?: X)?|Android|Windows(?: NT)) |(?:IEMobile|Version|webOS|Nokia\w+)\/)(\d+)[_.](\d+)(?:[_.](\d+(?:\.\d+)?))?/
    .test(navigator.userAgent) ?
  {
    major: RegExp.$1,
    minor: RegExp.$2 || '0',
    // let me introduce you BB10 versioning ...
    revision: (RegExp.$3 || '0').replace(/^0\./, ''),
    // compare with coercion
    // if (os.version == 7) {}
    // NOTE: the == instead of ===
    // works with other operators too
    // such os.version < 7 etc
    valueOf: function () {
      return this.major;
    }
  } :
  {} // unknown (some browser deos not expose the OS)

Tested With

• IE 10 Mobile and Desktop
• Chrome on Mac OS X
• Safari on Mac OS X
• Android 2.3.X, 4.3
• Blackberry Z10
• Nokia Asha 510
• webOS 2
• iOS 5.1, 6, 7

On Windows XP and Windows 7

• Firefox 24
• Chrome 30
• Opera 12

Please visit this test page and tell me if the result is correct (first line) and your OS is not mentioned in above list, thank you.

Firefox does not show the OS within its user agent. If there's an undefined value, most likely that's Firefox Browser/OS

All of these 3
these work for me
along with IE
on Windows XP
and Win7:

• Firefox 24
• Chrome 30
• Opera 12

updated, thanks!

Returns the OS version (10.9.0 under Chrome, Mavericks) for me... is this what it should? Wondering why it is assigned to "navigator.version" then. Wouldn't it be better called "navigator.osVersion"?

that's about the WTFPL :) Thanks.
P.S. yes, 10.9 makes sense, I haven't updated to that and I am on 10.8.5
