The Firefox 152.0 release binaries are now available ahead of tomorrow's official unveiling. With Firefox 152 there is now the JPEG-XL support code being compiled by default for the release albeit still disabled at run-time by default behind a preference for now.

Merged for the Firefox 152 release cycle was this change to now build the JPEG-XL image format support code by default on the beta and release builds of Firefox. Previously it was only enabled as standard on Firefox Nightly builds. Those interested in JPEG-XL on Firefox for now still need to go to the Firefox Labs to enable the preference but at least for beta/release builds the support is now compiled by default to ease the experimental testing.

Firefox 152 also pulls in the redesigned settings interface , HDR video support on Windows in different hardware configurations, CSS support for the field-sizing property, and a number of other developer additions as outlined on developer.mozilla.org .

It's next month's Firefox 153 release where there should be Vulkan Video decoding support .

Firefox 152 release binaries can be downloaded today from ftp.mozilla.org .
