Edit request headers (add, modify, delete) for any domain. Aims to be fast via creating hooks instead of analysing each request.
The options page gives you a simple ini-file editor, where each section represents a pattern, e.g., `https://*.example.com/`, & each key-value pair in the sections corresponds to a header name (say, referer or user-agent).
If you leave the value of the key empty, such header will be removed from subsequent requests.
