- (2025-07-15) Martin Kis: Works beautifully, amazing have many options are available. Is a must for ultrawide monitor users!
- (2025-07-01) Matt G: If you set it to dark, you can't see the letters on the sidebar while playing
- (2025-06-07) Brownie: Actually brilliant! love using this when watching content that isn't scaled to my ultrawide monitor, no more of those pesky black bars!
- (2025-05-08) Egya Besa: good, 5 stars from Ghana, west africa. nice chromium extension
- (2025-05-01) Zohaib: Love it !
- (2025-04-20) Andrew Negativo: Nice
- (2025-02-26) Divyam Bindal: I really really really loved this extention, it is so lightweight and gets the work doen without a hickup, and if you tweak it enough, your whole screen virtually gets extended like a big video while the original video being the same. Totally recomended.
- (2025-02-24) 오누르에라이: Brings Back the YouTube Ambient Mode – Amazing Extension! I love this extension! For some reason, YouTube removed the ambient lighting feature from my account, but this extension brings it back perfectly. It makes the viewing experience so much better, especially when watching videos in windowed or cinema mode. If you're using an ultrawide monitor, it even adds ambient light on the sides in fullscreen where black bars would normally be, making it feel much more immersive! Plus, it works seamlessly with other YouTube extensions like Enhancer for YouTube, making them even better together. Thank you for creating this awesome extension!
- (2025-01-31) Pana: works great, even in cinema mode!
- (2025-01-24) Felipe O Silva: I just love it. Sadly in the last update, it doesn't resize. It cuts the video frame, put the effects and everything. To have it on the 113% that I need, I have to go manually on the menu and click on anything at all, that's the only way to have it resized atm.
- (2025-01-21) Swastik Jain (SSG): This is such an amazing extension to YouTube's orignal Ambient Lighting, I think it deserves more praise than this.... I request you can you develop this type of ambient lignting for more video streaming platform(s) like Disney+ and Prime Video.... That would be really amazing...
- (2025-01-12) Việt Hưng Nguyễn: this need more downloads, suggestion: make the text so its white when ambient is black and it black when ambient is white
- (2025-01-04) That Leno: Everything is working perfectly fine. Please just fix the search bar. It remains black while playing videos.
- (2024-12-31) joao vitor: Very good extension but can you fix the search bar? Thanks.
- (2024-12-09) Julian Božić: Actually amazing, definitely comes in clutch on an OLED monitor.
- (2024-12-01) Hybert: It makes all background pure black rgb(0,0,0) which makes it uncomfortable to read comments.
- (2024-11-22) Markus Heinelt: Working fine. Nice addition to Youtube!
- (2024-11-16) Vishwajit: Why it does not making search bar transparent, only problem is the search bar is in the solid dark color!! BTW its very cool & awesome
- (2024-10-13) Nico: Works perfect for ultrawide screens and widescreen content!
- (2024-10-02) Louis Holdsworth: Works really well but prevents HDR content being displayed in HDR? Disabling the extension gives the video much more vibrant colours. Hope you can figure it out! Thanks.
- (2024-09-15) Seyrani Efe Özdemir: OMG that works really really well! U should start to use this right now.
- (2024-08-10) ً: Wished it work during fullscreen.
- (2024-08-09) harshil: actually the thing that I've wanted, thanks devs.
- (2024-08-01) Cicel Clenci: Must have if you have a oled monitor.
- (2024-07-11) sabaya edwin: honestly the best
- (2024-07-10) SmithAndrew 1: only used it for 15 minutes but LOVE IT!, solves the no ambient mode in theater mode problem. Looks incredible! Thank you!
- (2024-06-24) Temirlan Dair: Wow! This is so great extension! So, when does it come to all video player sites? If it comes, of course.
- (2024-06-21) Benjamin: Wow this works well, thank you!
- (2024-06-14) Vixxins: very good but is there a chance you could make this accesible for all video players like on netflix, prime video, disney plus? for the people with ultra wide screens we get black bars on the sides of al our videos and ambient light really helps ignore those black bars
- (2024-06-14) Endy Chin: Although it lags my video, which i definitely consider it as my Wi-Fi issues, there aren't anything that are needed to be improved. I highly recommend this extention for everyone.
- (2024-06-10) Scott Connors Jr.: Great extension - developer has provided a guide to work with RTX HDR.
- (2024-04-28) Cris Formage: Honestly transformed my YouTube watching experience. Coupled with a 32" 2k monitor, although not exactly like an ambilight TV, it does look nice in its own way. The "Remove black bars" doesn't work the best, as it can remove some subtitles that are actually within the video, like another user commented below. I just decided not to use it so it's not a huge deal. One problem I've been having recently though is: I exclusively use the theater mode with the setting "Hide everything in theater mode" enabled. For the past couple weeks, the video title has been visible at the bottom part of the page. Seems like there's problems with spacing when scaling. I'm not sure if it's the resolution or the size/aspect ratio of the monitor but it's a bit annoying. Can eliminate it by right clicking the title, then inspect, and then increasing line height to 5rem but I'd have to do that in every single video. Any fixes for this?
- (2024-04-13) N. H.: This is my second must have extension on a browser after adblock. Not only is the ambient light much better than youtubes, but it also completely declutters youtube when watching with "hide everything in theatre mode" enabled. I can never go back to normal youtube. This extension needs much more exposure!

- (2024-04-13) Sri Charan: The extension messes up the colors of any video I'm watching. Are there any settings that can prevent this? Edit: Thanks for responding, Wessel! It was clashing with the BetterTwitchTV extension. Not sure how but I've disabled that one. Thanks for the help. I can't use YT without this extension on my OLED monitor. Edit: I spoke too soon. The issues have continued. I've disabled all my other extensions yet the issues persist.
- (2024-03-31) JustDom: I use this to remove the ambient light feature. It does work. It does work so well that it removes dark parts of the video as well which often removes built in subtitles in the video as well..
- (2024-02-29) Jake: must have for theater mode users, so much better than looking at the default black bars. The developer is also doing a great job with adding features and fixing bugs. Overall a great QoL extension for youtube that doesn't slow down or dramatically change the site.
- (2024-02-23) Hải Đặng: wonderful, my Youtube is like being born again, beautiful and gorgeous like a princess, thank you author
- (2024-02-21) Chris Hall Aka Prize Gotti: Was confused as to why such an extension exists when YouTube has its own ambient light mode built in, but this is far superior to the default ambient mode. This really shows you the colors and much better detail can be seen. YouTubes built in mode is very dim and very blur by comparison. Good work!
- (2024-02-19) Craig Wolf: Looks great! Highly recommend this extension for owners of 21:9 QD-OLED monitors who view a lot of 16:9 full screen content to help prevent burn-in.
- (2024-02-09) Owen Glasspole: Great! Would love it if a version was made for Twitch
- (2023-12-04) boO mLa: Pefect :) Works like a charme and youtube looks great. Thank you and keep up the good work.
- (2023-11-09) Quang Dai: I felt awful for doubting this extension! Initially, I wondered why I needed this when YouTube already supports ambient mode natively. But oh my, with this extension and the customizations it brings, it takes the experience to a whole new level as long as you fine-tune it to your preferences. There are customizations beyond expectations that you can come up with. Respect to the person who created this!

- (2023-10-14) Wim Kuiper: This is such an amazing extension! It really gives a pleasant YouTube viewing experience, with a handful of customisation options at hand. I've got one question though: will you implement ambient theme to YouTube shorts and the YouTube home website? Definitely recommend!

- (2023-08-24) Simon: Very cool plugin as a replacement for the cinema light from Youtube. However, for some time now I have had the problem that I always have black bars on the left and right in cinema mode. For a while I had the ambient light on the sides in cinema mode as it should be. Now there are only black bars there. But the plugin still works at the top and bottom. And then I have another problem, namely that not everything is hidden when I activate the "Hide everything" function. Only everything above the video is hidden, only below. I hope there will be another update.
