Used Package Manager

pnpm

Expected Behavior

This issue seems to be only limited to firefox developer edition. Would love insight as to why this is the case?

Actual Behavior

The root loader gets triggerred over and over for this which should only occur once

I'm not sure what installHook.js.map is but if you want ot avoid Remix handling this request you will need to handle it yourself (or return a 404) prior to hitting the Remix handler. If you're using using remix-serve you will need to switch to use your own express server so you can handle this request.

installHook.js.map is part of React Dev Tools for Chrome and Firefox, disabling the extension resolves this warning/error.

The extension is making a request for a sourcemap that doesn't exist, which causes Remix to try to handle that file.

Not just Firefox Dev but also Firefox main. React Dev Tools is really nice to have. Why is this happening with new Remix apps?
