Tested using https://www.browserleaks.com/javascript, `userAgent` and `appVersion` are not spoofed. Currently I'm using [User-Agent Switcher for Google Chrome](https://chrome.google.com/webstore/detail/user-agent-switcher-for-g/ffhkkpnppgnfaobgihpdblnhmmbodake) but it only spoofs `userAgent`. v1.0.8.0 on Chrome 51.0.2704.79
