Not transparent

the only one that's really working, good job!
can we get a more transpartent one though?

Looks good with the new "Australis" update. Thanks!

everytime there is a firefox update I have to delete restart and add it again...

This is just what I was searching for! Took me a while until I found it though... Great job and thank you!:)

Es excelente cómo le dá la transparencia,, pero te cuento que a veces falla este tema y todo se vuelve de un color blanco,, y para resolverlo tengo que eliminar el tema y volver a agregarlo,,,,
