Why Firefox Still Matters

In a web dominated by Chromium monoculture, Firefox stands as the last major independent browser engine. It's not just an alternative—it's a statement that the web belongs to users, not corporations.

🔥 What Sets Firefox Apart

  • Independent Engine — Gecko engine developed by Mozilla, not Google
  • Open Source — Complete source code available, auditable, and forkable
  • Privacy by Design — Enhanced Tracking Protection enabled by default
  • Extensible Architecture — Rich add-on ecosystem with powerful WebExtensions API
  • Non-Profit Backing — Mozilla Foundation prioritizes users over profit
  • Standards Leadership — Actively shapes web standards for user benefit

Essential Privacy Configuration

Firefox ships with decent privacy defaults, but true sovereignty requires deeper configuration. Here's how to unlock its full potential:

🛡️ Enhanced Tracking Protection

Navigate to Settings > Privacy & Security

  • Strict Mode — Maximum tracking protection
  • Block All Cookies — Or use "Cross-site tracking cookies"
  • HTTPS-Only Mode — Force encrypted connections
  • DNS over HTTPS — Encrypt DNS queries

⚙️ Advanced Configuration

Type about:config in the address bar:

  • privacy.resistFingerprinting → true
  • network.cookie.sameSite.laxByDefault → true
  • dom.security.https_only_mode → true
  • network.dns.disablePrefetch → true

Firefox Hardening Profiles
