BROWSERS
Beware: apparently many (most?) websites ignore 'do not track' requests and track you anyway!

FIREFOX
My personal choice. On Win10/11 Microsoft tries to usurp this with Edge , and can make installtion of competing browsers such as Firefox impossible.

CHROME (Windows, Mac, Linux)
From Google.

 OPERA (Windows, Mac, Linux)
Opera originated browser tabs, and includes an email client. Not as good as it used to be.
