Firefox 153 Enables Containers by Default, and You Can Create Your Own - Here's How

Mozilla’s latest browser release makes Containers opt-out and asks permission before websites can reach local devices and services.

  • Mozilla released Firefox version 153 with Containers enabled by default, providing users four pre-configured containers: Personal, Work, Banking, and Shopping.
  • Containers isolate tabs to prevent information leakage between sites, stopping websites from snagging data to create user profiles or fingerprints.
  • Another addition to Firefox 153 is local network access restrictions, which prompt users before allowing sites to connect to routers, printers, and other devices.
  • Within Settings, users can enable container selection for each new tab, though as journalist Jack Wallen noted, "This is one feature that's not enabled by default."
  • For users seeking improved security without using Tor Browser, Firefox serves as a practical middle ground and is available for download from the official Mozilla site.
