HDR video playback comes to Firefox on Windows

Hello everyone.
We are excited to announce that Firefox version 153 now supports HDR video playback on Windows. If you have an HDR display, HDR content from sites like YouTube will now play back with the original intended brightness, contrast ratio, and color range. Previously, videos were downscaled to SDR.
This feature is enabled by default. Just update to Firefox 153 and make sure HDR is turned on in your Windows settings, and you're good to go.
This was one of the most requested media features for Firefox on Windows. Please let us know in the comments below how it works in your environment!
Requirements:
Firefox 153 or later
Windows 10 or 11
HDR-supported display with HDR mode turned on in Windows Settings > Display
No additional Firefox settings, flags, or configuration changes required
Details:
Supports HDR video streams and files using BT.2100 HLG and BT.2100 PQ color spaces (commonly known as HDR10). These formats are used for HDR videos on various websites, including YouTube.
Works on all hardware that supports HDR.
Known limitations:
Laptop displays that only support "HDR video streaming" (not full HDR mode) are currently not supported.
Some smartphone recordings shot in a specific direction may not currently display as HDR.
Brightness on some displays: Firefox does not perform tone mapping (tonemap) for HDR videos in this release by design. On displays with limited HDR headroom (maximum brightness limit), very brightly graded content (e.g., some music videos) may appear brighter in Firefox than in other browsers that support tone mapping. Some users have expressed a preference for this rendering method. We plan to add a display recognition tone mapping feature that users can control directly in future releases.
Frequently Asked Questions (FAQ):
How can I check if it's working? Play an HDR video on YouTube. On an HDR display, the HDR version will be displayed in the quality menu, and you should easily notice the difference in highlights.
What sites are supported? It is supported on all sites that provide HDR10 or HLG videos through Firefox. Since each browser determines which streams to send, support may vary by service.
There seems to be a problem with my settings. What should I do? Let us know in the comments or file a bug at https://bugzilla.mozilla.org/ including the GPU you are using, your display model, and the video link. In Firefox 153.0.1 (about a week after the release of 153), HDR details of your display will be added to about:support to help troubleshoot issues. Bug reports were instrumental in directly fixing bugs during the beta testing period.
Thank you for using Firefox!
