New privacy oriented feature added to Edge 82 - Freeze User-Agent request header

New in Microsoft Edge Version 82.0.421.0 (Official build) canary (64-bit)

Reason for doing it is more about privacy and stopping fingerprinting.

Freeze User-Agent request header

Set the User-Agent request header to a static string that conforms to the current User-Agent string format but only reveals desktop vs Android and if the 'mobile' flag is set – Mac, Windows

#freeze-user-agent

to be more effective, also enable this flag:

Reduce default 'referer' header granularity

If a page hasn't set an explicit referrer policy, setting this flag will reduce the amount of information in the 'referer' header for cross-origin requests. – Mac, Windows

#reduced-referrer-granularity
