Inspecting headers of file download

I compile a custom version of Firefox for personal use, and want to understand where to find something in the source code that I can't seem to find myself from documentation or manual searching.

I want to programmatically (i.e. from within the Firefox source) inspect the HTTP headers of all file downloads I initiate, potentially preventing the download if I see a certain header value. Anyone have a good idea of where in the source to do this?

I think that extensions are able to do this via the Web extension API, so no need to modify Firefox.
