[Bug] HTML is empty with dev:firefox

[qaptivator]

Describe the bug
Just trying out this project on my machine, i installed dependencies, ran npm run dev:firefox, loaded the extension manifest and all the menus, popups, startup and so on are completely blank.
I checked the generated html and the body was empty.

I ran the dev script but with chrome this time, and it worked perfectly.

To Reproduce
Steps to reproduce the behavior:

1. Run this

npx degit mubaidr/vite-vue3-browser-extension-v3 my-webext
cd my-webext
npm install
npm run dev:firefox

2. Go to debugging, "this firefox", load temporarry add-on...
3. Right after that, the startup opens but it's blank. Same with every other page.

Expected behavior
should just work.

Screenshots
no need for that, it's just all plain white. empty html.
