I used to use one (pretty basic one that turned everything white with some black trees) but ever since firefox made the redesign with the large tabs it feels like there isn't much need for themes anymore.
A given mission, mechanical assault, manufactured devotion.
Red eyes, an upside-down form. Even the twisted shape was made to be that way.
No matter how cruel the slaughter, worse than a demon's,
or how gentle the kindness, greater than an angel's,
a machine has neither will nor madness—only code, and a few bugs.
So why, then, does it feel so unbearably sad?
