Already using QuietBlock?
Back up its source folder. Replace the contents of that same folder with the contents of the extracted folder containing manifest.json, then click Reload on its existing Chrome extension card. Keeping the same folder and installation preserves settings and any historical totals. Version 1.7 uses a per-page count; previous totals no longer increase.
Loading SafeBlock from a different folder creates a separate installation. Removing the old extension can erase its saved data.
Compatibility and testing
SafeBlock 1.7.0 was submitted to the Chrome Web Store for review on 12 November 2026. Approval is pending. You can test it as an unpacked extension. It is not a signed iOS app. Chrome on iPhone and iPad cannot load it. YouTube filtering remains experimental; some ads may still appear.
56 automated checks passed. The installed Chrome dashboard and compact popup were checked. A controlled test completed a local request while three bundled ad/tracker requests failed and Chrome’s SafeBlock counter showed 3. This is a limited test, not proof of comprehensive live ad or YouTube coverage.
