Troubleshooting

Common symptoms

• Extension not loading — clear cache, then reload in chrome://extensions/
• Feature not working — open the console (right-click → Inspect) and look for [FocusTube] errors
• Storage not updating — reload the tab after changing settings
• A domain isn't blocking — check spelling; subdomains are covered automatically
• Block page not showing — check the browser console for errors

Enable debug logs

// In src/content/core/logger.js
const DEBUG_LOGS = true;

// Output appears as:
// [FocusTube] [Module] message

Inspect storage

// From the extension's DevTools console:
chrome.storage.local.get(null, (data) =>
  console.log('All storage:', data)
);
