* Mode 2: invert colors, normal (high) contrast
* Mode 3: reduce contrast only
* Mode 4: disabled
* Mode 5: inverts colors of text and images (useful for pages containing diagrams with text, but not photos).

The settings are saved separately for each website.

Right click the button to access the Options page, where you can change the default mode (for all pages).

Yensama Yen (ID: 00000059ae030385) Voted 5 ★ - Updated 08/23/2023 This is very good. So far works on most sites I have used. The only downside is that on some sites, it would also invert images(videos) making them impossible to see. e: the addon works as intended but it crashes a lot when alt tab with some programs. Mainly fullscreen game i think. other addons dont crash.

John Weiss (ID: 000000627bc3b61f) Voted 4 ★ - Updated 04/21/2023 Seems to have a bug. Clicking the button doesn't change the mode. However, default mode works.

Lyubomir Dobrev (ID: 0000009325e7f3cd) Voted 5 ★ - Updated 03/31/2023 Rock-solid extension. 5 modes to switch from with just a click. Never fails to blacken any website, unlike other extensions. It does invert photo and video colors on some sites, though, so you'll have to flip back and forth sometimes. Not a problem for me at all. This is a literal eye saver, so big love from me!

Bruno Melgarejo (ID: 000000ee09babee8) Voted 3 ★ - Updated 01/29/2023 Please add the function to disable the extension on specific websites (those that already contain the dark theme, for ex. youtube, gmail, facebook etc)
