Firefox 153 adds initial Vulkan video decoding
- Sources: Firefox 153 release notes, Phoronix, HN discussion
- Summary: Firefox 153 shipped on 2026-07-20. Per Phoronix coverage it adds initial Vulkan video decoding as a cross-vendor alternative to VA-API, experimental JPEG-XL through Firefox Labs, HDR video playback on Windows, and PDF improvements.
- Why it matters: Vulkan video decoding gives Linux systems without working VA-API a hardware-accelerated decode path independent of vendor VA-API support.
