Firefox Privacy Notice

Seriously Private Browsing

The most powerful private browsing mode with added tracking protection.

  • Private Browsing

    Firefox blocks online trackers while you browse and won’t remember your history after you’re done.

  • Tracking Protection

    Some ads have hidden trackers that follow you online. Rude. We know. That’s why our powerful tool stops them cold.

  • Faster Page Loading

    By blocking some ads and scripts that bog down browsing, pages load up to 44% faster. Now that’s a win-win.

Sync all your devices with a Firefox Account

Take your privacy, passwords, and bookmarks with you wherever you go.
