About Simple Modify Header
# Chrome Web Store Listing (English)
## Extension name
Simple Modify Header
## Short description
Add, override, or remove HTTP request and response headers locally with profiles, URL filters, and import/export.
## Detailed description
Simple Modify Header is a Manifest V3 extension for development, testing, and API debugging. Maintain Header rules in a focused panel and keep only the profile you currently need active.
- Add, override, or remove HTTP request and response headers
- Limit rules with URL contains filters or Chromium-supported regular expressions
- Create multiple local profiles and switch between them quickly
- Autosave and update browser rules about one second after editing stops
- Import or export local configuration JSON for backup and migration
- Use the interface in Chinese or English
- Keep local configuration when the extension is disabled
Privacy and security boundary: configuration remains in `chrome.storage.local` on your device. The extension has no account, cloud sync, content scripts, advertising, analytics, or remote code, and it does not send configuration or visited URLs to the developer or third parties.
Please note: Header rules may contain tokens, cookies, Authorization values, or API keys. Use the extension only on trusted devices and protect exported JSON files.
