CustomHeaders - Modify HTTP Headers Extension

A clean and simple extension that allows updating/modifying outbound HTTP request headers. No complex configuration options, no spam, and no distractions. For more complex requirements, there are other extensions, but this extension is a free extension to allow you to simply configure outbound headers.

** What does CustomHeaders do?**

- Add and modify request headers on all outbound requests.
- You can set HTTP headers such as Accept-Encoding, X-Forwarded-For, Pragma, Authorization, Access-Control-Request-Headers & other CORS headers, Content-Security-Policy (CSP), and any custom headers.
- Add and modify cookies.
- A clean and simple interface.

** What does CustomHeaders NOT do?**

- Insert ads into any pages, access your data, or do anything else beyond setting headers.
- You cannot set the 'host' header - this extension uses Chrome's declarativeNetRequest' feature, which doesn't seem to support changing the host.
