Almost 5 stars, BUT... Puntuado con 2 de 5 estrellas
One of the nicest-looking dark themes in years (love the transparency!) HOWEVER, it has the one theme-killer issue nearly all dark themes share;- the white text on the black background is not bold enough and ends up flickering. The flicker is hard on the eyes and distracting as heck. The only dark theme that ever got this right was Aquatint Black Gloss (2008-2010ish), but sadly the developer has moved on in life. Perhaps there's some work-around in FF to make the text bolder that I could use?
I'm sorry you are experiencing problems
I'm unaware of the flicker you speak of. Send me a screenshot? and I will see what I can do. :)
