Blackout by Czar16

Blackout brings dark mode to every website, even the ones that don't support it natively.

Browsing bright, white pages at night straining your eyes? Blackout inverts and adjusts colors on any site with a single click from the toolbar — no per-site setup required.

Features:

One-click dark mode toggle on any website
Works instantly, no page reload needed
Remembers your preference per site
Lightweight — no impact on browsing speed
No data collection, no tracking, no ads

Why Blackout? Most "dark mode" extensions are heavy, buggy, or break page layouts. Blackout is built to be simple and reliable: turn it on, browse comfortably, turn it off when you don't need it.

Your privacy matters — Blackout doesn't collect, store, or transmit any of your data. Everything happens locally in your browser.

How to use:

Click the Blackout icon in your toolbar
Toggle dark mode on for the current site
That's it — your eyes will thank you
