The Windows version of Firefox 153 beta adds HDR video playback, a feature that has been available on macOS since 2022. The official release is scheduled for July 21, 2026. HDR playback works on Windows 10 and 11 with AMD or NVIDIA GPUs and HDR displays, but excludes laptops with Intel and NVIDIA processors. A brightness difference compared to Edge and Chrome is noted and scheduled for future improvement.
Firefox has supported HDR video on macOS since May 2022, but Windows users had to wait until the 153 beta, released June 17, 2026, to get the same capability. The beta, now available for testing, enables HDR video playback on Windows 10 and 11 systems with an AMD or NVIDIA GPU and an HDR-compatible display. Laptops with Intel and NVIDIA processors are explicitly not supported. The development team has also published a technical retrospective on the implementation and stated plans to extend HDR support to photos, apps, games, and general web content in the future. A known issue where HDR video appears brighter than in Edge and Chrome is expected to be addressed in a later release.
