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.

Just enough details in the pic to look gorgeous, yet the tab titles still stand out without effort. Very well done!

I love this! Looking forward to seeing more themes from you.
