Contribute: You can view the source code and contribute to this open source project at https://github.com/WesselKroos/youtube-ambilight Privacy & Security This extension only runs on tabs that start with the url https://www.youtube.com. The extension will only activate the ambient light effect on YouTube's /watch page The only requests being sent are crash reports. (But crash reports can be turned off.) No other requests are sent to any webserver, website or api. But in case a crash occurs the report is sent to Sentry.io and will always be deleted after 30 days. Because the only goal of these crash reports is to fix the crash. While doing so we also take into account your Do Not Track preference.

The motion smoothing is really bad compared to my Samsung TV's motion smoothing.

In full screen there's a loss in contrast and saturation, otherwise I like the extension.

It makes all background pure black rgb(0,0,0) which makes it uncomfortable to read comments.
