• Useful for Development
  Highly beneficial for developers and testers who need to simulate different environments, bypass certain restrictions, or test API behavior with custom headers like CORS or authentication tokens.
• Rule-Based Automation

Possible disadvantages

• Security Risks
  Modifying headers improperly can expose sensitive information or create security vulnerabilities if used carelessly, especially when testing on live production sites.
• Learning Curve for Advanced Rules
  While basic header editing is simple, setting up complex rule-based automation with conditions can be confusing for beginners unfamiliar with header syntax.
• Potential Browser Performance Impact
  Running multiple active rules simultaneously might slightly affect browser performance or cause conflicts with other extensions that also modify network requests.
• Limited to Browser Scope
  Since it operates within the browser extension sandbox, it cannot modify headers for requests made outside the browser environment, limiting its use for broader network debugging.
• Compatibility Issues
  Certain updates to browser extension APIs or specific websites with strict security policies may cause the extension to malfunction or be blocked from altering headers effectively.
