Support for meta-Tag `theme-color`

[idna001]

Hello, 

I would love to see in the next Firefox a support for the meta-Tag `theme-color`.

As some Extensions or other Browsers do. (Like)

If there is no available Color, I would just have my default theme set. 

Thanks for Upvotes or an Update 

It's the only thing I miss on Firefox
