🔹 Best Practices & Security Tips

While the MetaMask Extension is secure by design, your safety depends heavily on your actions. Always:

• Write down and securely store your Secret Recovery Phrase offline—never share it. :contentReference[oaicite:5]{index=5}
• Use a strong password to unlock your wallet and enable extra protections like biometric or hardware wallet integration.
• Avoid malicious dApps and phishing sites—only connect your wallet to trusted platforms.
• Consider using dedicated browser profiles or virtual machines for high-risk operations so as to isolate your wallet environment.

🔹 Troubleshooting Common Issues

If you’re facing issues with the MetaMask Extension (e.g., missing accounts after restoration, stuck transaction), here are quick fixes:

• Check you have the correct Secret Recovery Phrase and password—without them you cannot recover imported accounts. :contentReference[oaicite:6]{index=6}
• Ensure the extension is updated to the latest version and your browser is supported.
• Clear browser cache or reinstall the extension if UI glitches persist.
• For account access issues, verify if the account was imported via private key or JSON file (these need manual re-import). :contentReference[oaicite:7]{index=7}
