Modify HTTP request headers with focused, local profiles. ModHeader Lite is a focused, local-first tool for modifying HTTP request headers in Chrome. Create multiple profiles, add custom request headers, and control where each profile applies using selected tabs, included URLs, and excluded URLs. Profiles can be enabled or disabled independently, and matching profile counts appear on the toolbar badge. Features: - Create, rename, duplicate, enable, disable, and delete profiles - Add and manage multiple request headers - Limit profiles to selected tabs and URL patterns - Apply changes immediately using Chrome Manifest V3 rules - Store all configuration locally on the device - No account, telemetry, analytics, or developer-operated backend This version modifies request headers only. Response-header editing and import/export are not included.
