+## Common Issues & Solutions
+
+### Issue 1: Extension Won't Load
+
+**Symptoms**:
+- Error when loading unpacked extension
+- "Manifest file is missing or unreadable"
+
+**Solutions**:
+1. Verify `manifest.json` exists in the root of `browser-extension/`
+2. Validate JSON syntax: `python3 -m json.tool manifest.json`
+3. Ensure you selected the correct directory
+
+---
+
+### Issue 2: Popup Not Opening
+
+**Symptoms**:
+- Clicking icon does nothing
+- Popup appears blank
+
+**Solutions**:
+1. Check browser console (F12) for errors
+2. Verify `popup/popup.html` exists
+3. Check if popup.js has syntax errors: `node -c popup/popup.js`
+4. Reload extension: `chrome://extensions/` → Click reload icon
+
+---
+
+### Issue 3: Analysis Not Working
+
+**Symptoms**:
+- Status stuck on "Analyzing..."
+- No results appear
+
+**Solutions**:
+1. Open browser DevTools on the popup: Right-click popup → Inspect
+2. Check console for JavaScript errors
+3. Verify site has cookies/CSP to analyze
+4. Try refreshing the page and re-analyzing
+
+---
+
+### Issue 4: Content Script Issues
+
+**Symptoms**:
+- "Unable to analyze CSP" error
+- DOM analysis not working
+
+**Solutions**:
+1. Refresh the target webpage
+2. Ensure content script injection is allowed (not on `chrome://` pages)
+3. Check extension permissions in manifest.json
+4. Reload extension
+
+---
+
+### Issue 5: Backend Sync Failing
+
+**Symptoms**:
+- "Test Connection" fails
+- Findings not appearing in backend
+
+**Solutions**:
+1. Verify backend is running: `curl http://localhost:4000/api/health`
+2. Check JWT token is valid (login again if needed)
+3. Verify CORS is configured correctly in backend
+4. Check backend logs for errors
+5. Ensure `extension_findings` table exists (run migrations)
+
+---
+
+## Code Quality Checks
+
+### Syntax Validation
+
+```bash
+cd browser-extension
+
+# JavaScript syntax check (all files)
+find . -name "*.js" -not -path "./node_modules/*" -exec node -c {} \;
+
+# JSON validation
+python3 -m json.tool manifest.json > /dev/null
+```
+
+### Line Count Statistics
+
+```bash
+wc -l popup/popup.js        # 400 lines
+wc -l js/background.js      # 200 lines
+wc -l js/content.js         # 127 lines
+wc -l js/owasp-mapper.js    # 329 lines
+wc -l js/openphish-service.js # 185 lines
+wc -l settings/settings.js  # 130 lines
+# Total: 1371 lines
+```
+
+---
+
+## Security Considerations
+
+### Extension Permissions
+
+The extension requests these permissions (see manifest.json):
+- `activeTab` - Access current tab (minimal scope)
+- `cookies` - Read cookies for analysis (read-only)
+- `storage` - Store settings and findings locally
+- `webRequest` - Intercept headers (for CSP analysis)
+- `notifications` - Show security alerts
+- `downloads` - Export reports
+- `<all_urls>` - Analyze any website
+
+### Privacy Guarantees
+
+✅ **No Tracking**: Extension does not track browsing history
+✅ **Local-First**: Findings stored locally by default
+✅ **Opt-in Sync**: Backend sync disabled by default
+✅ **No Analytics**: No third-party analytics or telemetry
+✅ **User Control**: User decides what data to send
+
+---
+
+## Success Criteria
+
+The extension is production-ready when:
+
+- ✅ All 12 feature tests pass
+- ✅ No JavaScript syntax errors
+- ✅ Manifest V3 compliant
+- ✅ All referenced files exist
+- ✅ Backend integration working
+- ✅ OpenPhish integration working
+- ✅ OWASP mapping functional
+- ✅ Settings persistence working
+- ✅ Export functionality working
+- ✅ Error handling graceful
+- ✅ Performance acceptable (< 2s analysis)
+- ✅ Memory usage reasonable (< 50 MB)
