Vantagraph Greenify Autor: Mustafa Ihsan Albayrak (Miabeyefendi)

Black Firefox theme with a bright green accent. Pure black tabs, toolbar and menus, green highlights throughout. A clean dark mode theme with no image and no scripts, under 1 KB.

This Firefox theme colors every part of the browser. The tab strip, active and inactive tabs, the toolbar, the address bar and its focused state, dropdown and context menus, the sidebar, and the new tab page with its cards. All 37 theme colors Firefox exposes are set, so nothing falls back to a default grey and the browser looks finished from edge to edge.

A dark theme that stays out of the way. There is no background image, no script and no permission request. The whole package is under one kilobyte, so it installs instantly, never loads anything from the network, and looks identical on a laptop screen and on a 5K monitor.

Contrast was measured, not guessed. Text and icons keep a readable ratio against every surface they sit on, the active tab stays clearly separated from the inactive ones, and the address bar never disappears into the toolbar. Long sessions stay comfortable.

Vantagraph is a family of ten Firefox themes sharing one visual language, five dark and five light. Click the author name above to see the rest.
