Helium Void

A minimal, AMOLED-friendly dark theme for Helium Browser. Pure black frame with system-dark neutral grays — no eye-searing purple, no compromises.

Installation

Packed

1. Download the latest Helium-Void-x.y.zip from Releases
2. Open chrome://extensions and enable Developer mode (top-right toggle)
3. Drag the zip onto the page
4. Done

Helium unpacks it into your profile, so the zip is safe to delete afterwards.

Unpacked

If you want to edit the colors yourself:

1. Clone this repo, or unzip a release
2. Open chrome://extensions and enable Developer mode (top-right toggle)
3. Click Load unpacked → select the folder containing manifest.json

Important

Unlike the packed route, this one never copies the files — Helium re-reads that folder on every launch. Move or delete it and the theme goes with it. Keep it somewhere permanent, not Downloads or a temp folder you'll clear out later.

Note

• Helium doesn't always apply theme changes on extension refresh. If colors aren't updating, remove the theme and re-add it via Load unpacked. If it still won't load, fully quit and relaunch Helium first.
• Incognito windows are not affected — this is a Helium limitation, not a theme issue. Even the Void Theme from the Chrome Web Store has the same behavior.
• Built on Manifest V3.
