Before you start

Site Blocker stores your selected domains, blocking preference, and privacy choice in this browser.

It reads the current tab URL to offer “Block site” and checks open tab URLs when applying your list. The browser also matches website requests against your blocking rules.

All processing stays on your device. Site Blocker does not keep a browsing-history log or send your data to the developer or anyone else.
