HeaderPilot by Libin Thangam Jayaraj

HeaderPilot helps developers switch HTTP request and response headers for local testing.

Features:
- Colored profile pills for fast switching
- Import and export profile JSON (multi-file and paste)
- Request and response header editing
- URL filters and redirects
- Append mode and active-tab-only option
- Pause injection with one toggle
- Multiple UI themes

Intended use:
Development and QA only. Enable a profile when you need specific headers; disable when finished.

Permissions:
- storage: save profiles locally on your device
- declarativeNetRequest: apply header and redirect rules
- optional host access: requested only when you enable the extension

No remote code. No analytics. Data stays on your device unless you export it.
