Finally found it, the extension to help darken every page with no harass at all, it helps with ambient light problems, ex.: too much light in a room turn it on, too few turn it off, and just with a single click..
Thank You dlinBernard

удобно включать и выключать, и не глючит!

Works great on mobile

Ultra simple

niceeeeeee

Awesome extension. This literally saved my eyes

Good

I have been looking for a dark mode that works correctly for quite some time. I like that you can toggle it on and off quickly as well as the wide variety of dark styles under the add-on options.

Keep up the good work as I can no longer browse without dark mode enabled.

The style that seems to work well for most pages is the class b style: "Dark invert #5"

helpful and simple

Kruto!!!

very good

Cool !!! Thanks a lot , developers.

Excellent extension. Could you add the option to activate / deactivate button in the contextual menu of the Web page?

The developer of this application knows exactly what I need))

BEST. APP. EVER. PERIOD.
