1505203 - Consider extending webRequest.resourceType to sync with fetch destinations

Status: RESOLVED DUPLICATE of bug 1503898

(WebExtensions :: Request Handling, enhancement, P5)

Description

[April King [:April]]

I write a webExtension that is fairly widely used in the web security world to generate Content Security Policies. How it does this is by watching the webRequests that a site issues, looks at their details.documentUrl, details.url, and details.type, and maps that to a proper CSP report.

While this works for most things, it doesn't work for some things like workers, which would have a worker-src in CSP, but details.type has a type of "script".

It would be nice if either:

a) details.type (aka webRequest.ResourceType) would return what the fetch specification has for destination type ("worker"), or
b) details had an additional key (such as details.fetchType) that mapped to the fetch destination type

Thanks!

April, this seems like an easy win, but I'm going to loop Shane in for an engineering perspective.

I would add that I've figured out a workaround for my particular extension, but I still think this is the right (if low priority) thing to do and would benefit a number of other extensions.
