It doesn't look bad, but it certainly doesn't match the color scheme of breeze dark in plasma 5. It's far too light.

Beatiful theme

Not Dark.

I use this theme on Android. It looks every similar with my notification bar. Thx.

many thanks!

Since Firefox 46 and its activation of GTK+3 the Breeze-dark theme of Plasma 5 is quite buggy.
I changed the theme for GTK+3 apps to Adwaita and installed this Firefox theme. This seems to work out quie good so far.

Nice theme for a consistent look in Plasma 5 not only on Kubuntu but on other distributions as well.

Sadly, Firefox 44 added a new grayish glow to the current tab and the url, search & addon bar. Theme needs to be updated to override this somehow.

Great - thanks!

nice......thank you very much :)
