How do I block access to a website on Mozilla Firefox?

Bonjour Is it your question (e.g.) https://support.mozilla.org/en-US/questions/1585489 The Enterprise Policy Generator helps administrators configure Firefox using a configuration file https://addons.mozilla.org/firefox/addon/enterprise-policy-generator Enterprise Policy Generator – an open-source, browser-based approach to creating Firefox enterprise policies https://connect.mozilla.org/t5/discussions/enterprise-policy-generator-an-open-source-browser-based/td-p/127768

Hi Andrew An alternative is to contact your internet service provider who should be able to put a block in place for you.
