Privacy
What this means & what you can do.
What servers always see
Your public IP address, TCP/TLS fingerprint, requested URL, HTTP version, and all request headers are visible to the web server before JavaScript even loads. A VPN or Tor hides your IP; HTTPS hides the content but not the destination.
What JavaScript can read
Once a page loads, scripts can enumerate your screen, hardware, battery, timezone, fonts, plugins, canvas/WebGL signatures, and more. These values combine into a surprisingly stable fingerprint that works even if you clear cookies.
Use a privacy-focused browser
Browsers like Firefox with strict Enhanced Tracking Protection, Brave, or Tor Browser deliberately randomise or limit many of these signals. Tor Browser makes all users look nearly identical.
Container tabs & separate profiles
Use Firefox Multi-Account Containers, Chrome profiles, or temporary browser profiles to isolate cookies, localStorage, and caches between different online identities.
Deny unnecessary permissions
Location, camera, microphone, notifications, and clipboard access should default to blocked. Only allow them on sites you trust and only when actively needed.
Block third-party scripts
Trackers usually live inside ads and analytics scripts. uBlock Origin, NoScript, or uMatrix can block these before they fingerprint you. Disabling JavaScript entirely is the strongest defence.
