Resource Override (MV3) is an extension to help you manipulate HTTP traffic - Redirects, Inject scripts and modify http headers. This is Manifest V3 Version adapted from the original Resource Override extension built by Kyle Paulson here :- https://github.com/kylepaulsen/ResourceOverride/tree/mv3 Since Resource Override got deprecated and the author mentioned that he won't be working on the MV3 version, I adapted the work and built this extension to continue supporting the developer community. This is a completely free & offline extension. HTTP Resource Override allows you to redirect URLs on the fly before requests are made. This tool is great for debugging production websites, as you can edit and inject code on the fly. You no longer have to scan through minified code as you can just redirect to an unminified version or paste in the unminified version with the integrated file editor.
