Best ad-on to change the background brightness and color!!! and it's simple to use,,,once will do all websites.
Thanks very much.*john

It's good, and I think if two feature is added, it will be better.
1. Add some predefined color
2. The RGB values change along with the slider moving

Thank you for this add-on. It beats the heck out of fiddling with Windows 10 'Night Light' feature. So easy to use and the default (amber-like) color is near perfect for me. You can adjust the color mixtures, but If you like the amber, the 'opacity' slide control to make the color lighter or darker is all you need. The only thing I would add is way to restore the default color mixtures so you can start over.

I intend on contributing for the simple reason that this extension actually works for the better. Thank you, also friends of mine also are impressed.

this was the best extension ought there in the firefox market to adjust the color, brightness and opacity parameters. works perfectly , really thank you developer.

Works on all websites i tried, can customize every channel, and the brightness (via Opacity). The best

I thought that if the background is gray it is kind to the eyes. This way of thinking was wrong.
This add-on is correct!
- Cut the blue.
- Cut by default.
· Toggle cut with 1 click.
· You can also adjust the color.
Great!
