we've been struggling with v3 for months. But gathered some experience on the way. What is the problem? maybe I can help.
Discussion
so I launched zapworthy.com today
I have an extension that embeds a widget snippet on any site
but for it to work it needs access to window.nostr; when I move it to manifest v3 it doesn't allow me to inject a remote javascript, it wants me to bundle the javascript inside the extension, but then it doesn't execute in the context of the browser 😕
