content: I hate to say, but it feels like a loosing battle. Nevertheless....   I would avoid chrome cause it is google and google is in the business of tracking.   Same with Microsoft (go linux)  I would use firefox, or some derivative of it, or maybe something like brave browser.   Extensions and information provided by eff.org is a really good place to start.  (Privacy Badger, HTTPS)    . Seriously, EFF Is one of the few well organized fighters for internet freedom.      use protonmail, tutanota, or host your own e-mail, encourage others to do so.  setup and use use an alternate e-mail address (some services provide aliases) to sign up for random shit on the internet.     Oh and if you haven't already, remove everything facebook from your life.,.. (and your electronics)         EDIT:  I forgot, SIGNAL PRIVATE MESSENGER.... or some other encrypted peer to peer open source SMS messenger alternative.
