When I start the development version of the Polkadot.js extension on Firefox after installing it, I'm getting the error: File not found. Firefox cannot find the file on moz-extension://.../index.html.

Before installing I build the extension using yarn build as described in the README.md file. Starting the extension on Google Chrome does work.

How to start a development version of the extension on Firefox?

Fixed it by loading the index.html file instead of the manifest.json file. I created a pull request.
