That site uses some "cookie protection" that requires the client to first execute some JavaScript to set a cookie and make another request with that cookie. Unfortunately, FirefoxPWA client can't determine that cookie easily so the request will always fail and return a broken manifest.
When I implement support for installing non-PWA sites, I will also add a switch to force disable manifest usage, so that could be a workaround for installing this site.
I know it's not a solution but 4anime.to is honestly better than 9anime.
You will be able to uncheck "Use the manifest for determining app properties" when installing this site in the next release.
