What are the differences between Chrome and Firefox offline password extraction techniques?

Chrome uses Windows DPAPI to encrypt saved passwords, requiring the user's Master Key and login password for offline decryption. Firefox, on the other hand, uses its own key storage, often based on the Network Security Services (NSS) library. For Firefox, you may need to export the key database or use tools like the Firefox profile decryption method described in Penetration Techniques - Exporting Saved Passwords from Firefox Browser and Exporting saved passwords from Firefox browser via Network Security Services.
