Firefox 152 Now Available With JPEG-XL Support Built By Default, Modernized Settings UI

Written by Michael Larabel in Mozilla on 15 June 2026 at 11:15 AM EDT. 11 Comments

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.
