How to achieve deterministic builds with Webpack for Firefox extension?

Question

I am currently working on a Firefox extension, but I am facing an issue with webpack bundling. Since Firefox requires me to upload the source code of my addon, the reviewer must be able to create the same build as I did. However, I am encountering a problem where Webpack always creates a different build, which makes it impossible for the reviewer to replicate my exact build.

To be more specific, the builds are same on the same system, but when I make build on my Mac and then on Linux, they end up being different.

Here is my webpack config:

  mode: 'production',
  optimization: {
    chunkIds: 'deterministic',
    moduleIds: 'deterministic',
    minimize: false,
    runtimeChunk: false,
    splitChunks: {
      chunks(chunk) {
        return chunk.name !== 'contentScript'
      },
      minChunks: 3,
      maxSize: 3500000
    }
  }
})

Do you have any advices on how to solve this? If you have any questions, feel free to ask!
