Add-on summary

You can set, append and remove various HTTP headers on both request and response. This add-on differs from others in that it uses the MV3-compatible "DeclarativeNetRequest" API which means that the browser itself handles all the modifying logic.

NOTE: Modified response headers won't be shown in the network console but they are still applied.
