Use HeaderSmith – cod3rjava to override outgoing request headers directly in Firefox.

Features:
- Add multiple header rules (name/value) and enable/disable each rule
- Optional URL regex filter to apply rules only to matching URLs
- Rules are stored locally in the browser (storage.local)

Privacy:
- No data is collected or transmitted off-device.
- The add-on only modifies request headers for requests matching your configuration.

Notes:
Some headers may be restricted by Firefox and cannot always be modified.
