Firefox 153 Beta Released with Vulkan Video Decoding and JPEG-XL Support

Firefox 153 arrives in beta with Vulkan-based video decoding and native JPEG-XL image format support.

Mozilla has released Firefox 153 to the beta channel, bringing two notable technical additions to the browser. The release adds support for Vulkan-based video decoding, a graphics API that can offload video processing to the GPU for improved performance and efficiency. Firefox 153 also gains support for JPEG-XL, a modern image format designed to offer better compression and quality compared to older formats like standard JPEG. The beta release is available through mozilla.org's Firefox beta channel, with a stable release expected to follow the standard Mozilla release cycle.

Why it matters

Vulkan video decoding can improve playback performance and reduce CPU usage on compatible hardware, while JPEG-XL support broadens Firefox's compatibility with next-generation web content.

What's next

Firefox 153 beta will progress through testing before a stable public release in line with Mozilla's roughly four-week release cycle.

Key facts

• Firefox 153 has entered the beta release channel
• The release adds Vulkan API-based hardware video decoding support
• JPEG-XL image format support is included in this release
• Coverage comes from Mozilla's official Firefox release page and Phoronix, a Linux and open-source hardware publication

Bias & framing notes

Both sources agree on the two headline features — Vulkan video decoding and JPEG-XL support — but neither source body text was available, so specific implementation details, platform availability, or any caveats cannot be verified. The Phoronix headline frames it as a full release while the Mozilla source labels it a beta, which may indicate a minor discrepancy or a timing difference between beta and stable channels.
