ISH Whitelist-Block install.sh מאת

ISH Whitelist is a lightweight site blocker for Firefox. It allows you to restrict browsing to a user-defined whitelist of websites and helps preserve profile specific browsing contexts.

Useful for privacy focused Firefox users who work with multiple browser profiles and want to keep browsing contexts separated. ISH Whitelist helps restrict each profile to its intended websites and avoid accidental cross-context browsing.

When a visited website is not on the whitelist, the browser redirects it to the first whitelist entry. If the whitelist is empty, no websites are blocked.

The add-on provides a small browser popup where you can add, remove, edit, and reorder whitelist entries.

Simple by design: focused and free from unnecessary option or menu overload.
