Extensions That Matter

A few carefully chosen extensions improve security and privacy. On Firefox or Brave, the full uBlock Origin remains a strong content blocker. On Chrome, Manifest V3 means most users should choose uBlock Origin Lite or another MV3-compatible blocker instead. A password manager fills credentials securely and resists fake login pages.

Be extremely selective about extensions. Each one you install can potentially read everything you type and every page you visit. Only install extensions from reputable developers with large user bases. Review permissions before installing, and remove any extension you no longer actively use.
