#🔧 Troubleshooting

##Common Issues

###Extension Not Working

1. Check permissions: Extension needs access to coursera.org
2. Reload extension: Disable and re-enable in browser settings
3. Check console: Open Developer Tools → Console for errors

###AI Backend Connection Failed

1. Start backend: Run ./start_backend.sh
2. Check port: Ensure localhost:8000 is available
3. Firewall: Allow Python through firewall if needed

###Questions Not Detected

1. Page loading: Wait for page to fully load
2. Question format: Some question types may not be supported
3. Manual selection: Use speed controls and manual answer selection

###Low AI Accuracy

1. Install better AI: Add Transformers or OpenAI integration
2. Check question domain: AI works best on technical subjects
3. Review confidence: Low confidence answers may be incorrect

##Testing & Validation

# Test AI backend
python advanced_test.py

# Check backend health
curl http://localhost:8000/health

# Restart backend if needed
./start_backend.sh

#📊 Performance & Stats

##AI Accuracy by Provider

#🛡️ Safety & Ethics

##Academic Integrity

• Check institution policies: Ensure automated tools are allowed
• Use for learning: Don't let automation replace actual learning
• Verify answers: Always review AI suggestions
• Original work: Use for assistance, not replacement

##Privacy & Security

• Local processing: Heuristics run entirely locally
