Description
Create and manage custom HTTP request headers for selected websites or all websites. Modify Request Header is a simple developer utility for creating and managing custom HTTP request headers. Features: - Create multiple request header rules - Enable or disable individual rules - Set a target URL for each rule - Leave the URL blank to apply a rule to all websites - Import and export rules using JSONL files - Store configuration locally in Chrome The extension modifies HTTP request headers only according to rules explicitly configured by the user. The extension does not collect browsing history, website content, analytics data, or usage statistics, and it does not transmit header configurations to external servers. Important: Header values may contain sensitive information such as API keys or authorization tokens. Exported JSONL files contain these values in plain text and should be stored securely.
