This extension allows users to customize and override HTTP request headers in Firefox. Each header modification includes:

• Header: The key of the HTTP header (e.g., User-Agent, Accept-Language).
• Header Value: The custom value to be sent with the header.

Key Features

• Manage headers via a simple React-based popup interface.
• Rules are stored in Firefox's local storage for persistence.
• Applies modifications dynamically using Firefox’s declarativeNetRequest API (updateDynamicRules).
• Compatible with Manifest V3.

Ideal for developers, privacy-conscious users, and anyone needing fine-grained control over request headers.
