TensorFlow.js in love with YouTube and Chrome extension

It’s a ‘just for fun’ project for motion tracking in YouTube videos.
Available in the Chrome Web Store.

I am grateful for any feedback.

And so far I have only tested it with MacPro 2021. Everything runs very smoothly. Maybe someone has older hardware available for testing and can write something about the performance.
