Navigator

 JS.Navigator is a set of Javascript objects that stores various parameters and their values that describe specifics of a computer it executes on. All JS.Navigator object parameters are freely accessible by a browser. Since they possess certain uniqueness, especially when combined, websites may utilize these parameters for user fingerprinting and tracking. 

Websites may also analyze these properties for consistency to reveal cases of fingerprint altering. Such analysis may reveal the usage of browser fingerprint randomizers such as Random Agent Spoofer Firefox add-on.

User-agent

A User-Agent is a short string native to the browser. By reading a User-Agent string,  a website is able to identify your browser and operating system versions. 

This is an example of a User-Agent value:

Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.2785.8Safari/537.36

In this case, the website will assume that the user is using Windows 7 and Chrome version 62. “NT X”” is the version of a Windows release. You may check other release versions from a Wikipedia article

When creating a browser profile, an User-Agent value will be retrieved from a fingerprint database. An operation system filter from the Overview page will be honored. You may check the User-Agent value of a browser profile on the Navigator page.

If you do decide to configure User-Agent manually in Incogniton, make sure to set a corresponding Platform value. Discrepancies in User-Agent and Platform values are a big red flag. 

Platform

The platform property is a Navigator object parameter which tells for which platform the browser was compiled.

When creating a browser profile, a Platform value is retrieved together with an User-agent.  Both values are affected by the Operation System filter from the Overview page.  You may also set this value manually on the Navigator page.

If you do decide to configure Platform manually in Incogniton, make sure to set a corresponding User-Agent value. Discrepancies in User-Agent and Platform values are a big red flag. 

Possible Platform values for desktop browsers:

Linux i686
MacIntel
Win64
Win32

Possible Platform values for mobile browsers:

iPhone
iPod
iPad
Android

The full list of possible Navigator platforms can be found in the application.
