Every browser extension you add increases your attack surface. Each one gets access to your browser environment, sometimes more than you realize. Question if you really need the extension. Always review permissions. Audit your extensions regularly and delete what you don’t use.

Final thought: Every extension is a trade-off: function versus exposure. Use only what you need. Trust no default settings. The less you reveal, the safer you are.
