Block any website by typing its domain. Toggle all blocking on/off with one switch.
Unlike most blockers, site-blocker-permissionless never asks for access to your webpages, URLs, or browsing data. It uses Firefox's declarativeNetRequest API so the browser itself enforces blocks — the extension doesn't see what you visit, type, or do on any page.
Features • Minimal popup: add or remove sites with one click • Master on/off toggle • Matches subdomains automatically (www, m, mobile, etc.) • No telemetry, no data collection, no network requests • Only permissions used: declarativeNetRequest and storage
