Prague Theme for Firefox

Inspired by Prague's midnight river reflections, gothic silhouettes, and warm lamplight on old stone, this theme pairs deep cobalt-navy shadows with cool steel blues for a calm, cinematic coding mood. Rich surfaces and crisp selections keep focus sharp, while a bright sky-blue accent and subtle golden highlights add contrast across tabs, hovers, and search matches.

A dark theme from the Codigrate Cities collection, released 2026-02-04. Tags: Gothic, Historic, Timeless.
