What steps do you take to secure your online use and privacy?

I do the following:

• Use a VPN (NordVPN)
• Use Firefox with a tweaked about:config and the following security extensions:
  • uBlock Origin
  • NoScript
  • HTTPS Everywhere
  • Privacy Badger
  • Decentraleyes
  • Cookie Autodelete
  • Skip Redirect
  • CanvasBlocker
• Run Linux Mint (I know, Ubuntu-based distros aren't ideal but I'm a Linux beginner)
• Don't have any social media as of a year ago
• Don't use any Google services, including YouTube, Google Search, or Gmail
• Use a password manager (KeePassXC)

The next step would be for me to switch from iPhone to Android running Lineage OS, but money is a bit tight right now. As for day-to-day lifestyle choices, I try to use cash whenever possible and never sign up for things like store rewards programs.

What's your setup? Do you consider yourself a privacy-minded individual? Are you more concerned with protecting yourself from corporate or government entities?
