I use it since years... The best one available on firefox... Thanks a lot dude !!
It miss only one feature which is Sharpness !!

Perfect extension to make videos darker at night. Thanks to developers. Mozilla should recommend this extension to reach more people suffering from eye strain like me.

Идеальное расширения для регулировки яркости в онлайн видео. Наконец-то я нашел такое.

Can you add a sharpen filter?

Use this for watching netflix on my external monitor which isn't bright enough. Works perfectly.

My Eys say Thanks to you!

all i need, thanks.

I was looking to brighten video playback for dark videos/streams. It does brighten the video but it slowed down my browser. Video playback was also affected. At first, I didn't know why videos/streams felt like it was skipping frames. Removed this add-on and browser + videoplayback was back to smooth. Be careful guys

Almost perfect, just what i want to tweak my video experience.

It would be nice if it wasn't that it lags out the videos.

Nice and easy to use, but honestly what I need most is some kind of sharpness filter.
Just got a 4k screen, and it's really made watching 1080p content on youtube a worse experience.
The perfect thing would be an integer option that could upscale 1080p to 4k, but don't know if that's even possible, or maybe a way to make the Nvidia edge enhancment work in Firefox, since it doesn't currently and hasn't for years.
Would be nice if the extension had the option for choosing what sites to work on, maybe with the possibility for different settings for each site.
Oh, and have the settings work in 1% steps rather than 10% for better adjustments.
Just my 0.02 regarding possible improvements. :-)

Been using this for a while, and I'm a big fan. To be honest, I don't tend to use it for night watching. I use it because sometimes sports events look different on different broadcasters' streams, and I want to make them the same. With this extension, all the reds and greens and blues can be exactly the right colour!

Wow simplemente practico para mejorar el video en la web, Netflix Youtube y demas

Thanks finally found a gamma filter.

ดีมาก
