This is very nice but you'll need to also make a custom userchrome.css to control the text color in the Status Bar. It won't be readable by default and Themes are unable to control this - it has to be done manually by the user.

e muito boa deixa a letra branca
eu to mais acostumado desse jeito
danifica menos minha visao
e agora o firefox se aproxima mais
do firefox do linux que eu usava
5 estrelas por trazer velhas lembranças

Looks amazing.

Very slick
