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.
