Great

Works flawlessly. Only thing that I'm missing is the ability to save settings per site.

all of the color and gamma etc options work great, but as others have mentioned, it bugs the video playback. playback becomes choppy and skips probably 3 out of 4 frames. disabling it immediately fixes the problem

Nice this is exactly what I needed, I used to use "youtube enhancer" filters to do this, but that extension was removed and I can't find the source. This is even better because its not limited to youtube. I also stared it on github, thanks for creating this!

Works great, but in full screen is slowed, please improvement.

Yes as said by another user, it slows down the video playback. Strange it works fine on my other higher OS. Please provide detailed information about performance issues on different systems and browsers.

Finally found an addon with gamma adjustment! Thank you! :)

Very nice, but I have to reload once to use the gamma correction feature.

best video color tuner, add an option to save settings as a profile if possible and easily restore from saved settings.

Please add a sharpness filter!

Works great when it's working, and I was hoping to roll this into my workstation toolkit - BUT it has a MAJOR bug that makes it completely unusable in practice: when using in conjunction with any fullscreen HTML5 player, this extension will prevent the GPU from correctly leaving (but not from entering) any of its sleep states - effectively crashing the entire system the second it goes to sleep, with the potential to brick the GPU and/or mobo bios any time it happens. Tested in clean installs of Firefox Quantum, Firefox ESR, Waterfox Classic, Waterfox G3 and Waterfox G4, on multiple fresh workstation images (1x W7 + 2xW10) each with different GPUs (GTX 970, RTX 2060, GTX 1080) and substantially different baseline configurations including drivers; 100% reproducibility on every one of them: everything system-wide is ship-shape and working 100%, but add this extension and let the browser idle until it goes to sleep = unresponsive system until hard reset.

Not usable in its current state for this reason.

Where have you been all this time? Works exactly like something that should have been included in the first place. And its so easy. man U deserve an award.
