Extension Metadata
About this extension
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
