About

Popup Dark Mode Toggle adds a simple, reliable theme switcher to the extension’s popup UI. With one click, users can switch between Light and Dark themes and keep that choice the next time the popup opens. This is ideal for extensions that want to demonstrate or ship a clean, accessible theme toggle without touching webpage content.

Why it’s useful

Immediate readability: Match your preferred contrast in low-light or bright environments.

Persistent preference: Remembers the last theme so your popup always opens the way you like it.

Drop-in pattern: A straightforward example of stateful theming for MV3 popups.

How it works

Open the toolbar popup.

Click the theme toggle to switch between Light and Dark.

The chosen mode is saved and reapplied on the next open.

Key points

Theme setting stored locally using the storage permission (no accounts, no cloud).

Runs entirely in the popup—does not inject scripts or modify websites.

Minimal MV3 footprint: popup + local preference storage.
