Use a PC. Get either Brave, Chrome, Firefox, or Tor if you're lazy. If you don't use Tor then get the following plugins/extensions: Canvas Blocker, Privacy Badger, uBlock Origin or uBlock Origin Lite, WebRTC Leak Prevent, Unshorten.Me, ClearURL, Tampermonkey, and set all your privacy settings to maximum.
The EFF has a Fingerprint Test for you to run. With those I always come back unique. It doesn't mean anything though. I've seen dozens of accounts get banned because my psychotic stalker accuses anyone who disagrees with her of being me and they get banned when I don't have any socks and Null has even put her in spergatory for that shit. You're really taking a lot of precautions for no real guaranteed safety. Remember, it's Green Reddit and they will ban you for cheese.
