The add-on stopped to work

The devs say they're not using the API, but this no longer seems to work since the API was nuked on Dec. 13th. It's a shame, because this was the only one that provided the ability to customize the bar to something more useful than grey-on-grey, like red-and-green. 😒

Even the few extensions that still work won't for long, Google will ruin those soon enough.
