Halora — Video Light for Firefox von ardidraws

Halora extends the colors at the edges of YouTube videos and Twitch streams into a soft, moving glow around the player. It is designed for transparent Zen Browser setups: keep your existing transparency or add adjustable page dimming.

Halora needs access to YouTube and Twitch to read video pixels and display the halo. All video processing happens on your device, and your settings stay in your browser. Video frames are never saved or uploaded. Halora has no tracking or analytics and sends no data to external servers.

Tune the reach and blur on each side, color and brightness, black pixel opacity, and rounded player corners. YouTube and Twitch can share settings or use independent profiles. Export and import your settings as a local JSON file.

The optional Halora Tabs for Zen Sine mod continues the light behind Zen's tabs. The Firefox extension works on its own without Sine, only the tab effect needs the companion mod.

Some protected streams prevent pixel sampling.
