The theme is NOT applied to the Firefox menu bar nor to the "list all tabs" drop-down menu.

This theme has nice use of nuanced contrasts, but having cyan used for the text AND tab border, AND tab highlight color is a missed opportunity to embrace the high use of subdued harmony used in the cyberpunk genre. Using one other color for those 3 like peach would have helped.

Lastly adding slight transparency to the URL bar would elevate the Cyberpunk feel.
