My World Maker, a manual mute button for the internet

Field notes

The extension applies user-written word rules to discrete page items such as posts, videos, search results, and headlines, removing matches rather than covering them. Rules can be separated into presets, scheduled—including overnight ranges—and temporarily bypassed for a timed visit to a blocked site. The page states that filtering stays on the device and that optional cross-device sync is end-to-end encrypted. It lists Safari, Chrome, Edge, Firefox, Firefox for Android, and Windows among its supported platforms.
