What is Modify Content-Type?

'Modify Content-Type' is a Chrome extension in beta phase, designed to let you manipulate the Content-Type and Content-Disposition HTTP header fields of incoming documents. You can force your browser to display the document or offer it as a download, or override unknown mime types with common ones like 'application/pdf' or 'application/xml'. It helps when handling documents from misconfigured servers.

I couldn't not get it to match on any filter expression. Tested my regex and it was valid. It just refused to change the content type. 🤷‍♂️
