I think I've got it for folks using electron-webpack. Solution was from a post related to importing codemirror. https://github.com/electron-userland/electron-webpack/issues/81

This worked for me.

// package.json
{
  //...
  "electronWebpack": {
    "whiteListedModules": [
      "firebase"
    ]   
  },
  //...
}
