this is a hilarious concept and i absolutely see the vision but it's not actually been edited to work with firefox, the references are still all for google chrome so it doesn't actually do anything.

also for an extension that asks for data on all sites i wish the extension page were clearer because not everyone can audit the code. However. im excited to see where this extension goes because i unfortunately DO need this in my life. (ps - it could be funny if the text replacement was with a span element with an image of the character rather than an emoji... hmmm...)
