- The change would make JPEG XL a standard, out-of-the-box feature for all Firefox users rather than an opt-in or experimental one.
Mozilla intends to enable JPEG XL support by default in Firefox 157 across all platforms, according to a discussion posted to the official Mozilla developer forum.
What the announcement covers
The decision, surfaced via Mozilla's dev-platform communications channel, signals that users on all supported operating systems will gain native JPEG XL capability without requiring any manual configuration. The scope of the change — described as applying to all platforms — suggests a broad, simultaneous rollout rather than a staged or platform-specific release.
Context and community interest
The announcement drew considerable attention from the developer community, reflecting ongoing interest in modern image format support within browsers. The underlying details of the implementation, any associated compatibility caveats, and the precise release timeline for Firefox 157 had not been elaborated upon in the available source material at the time of publication. Those points remain unconfirmed pending further disclosure from Mozilla. This follows a period of active development for the browser, which has also recently seen changes to search and security features — as covered in Firefox 154's addition of Startpage search and new security controls.
Significance
Should the plan proceed as indicated, Firefox 157 would mark the point at which JPEG XL transitions from an opt-in or experimental feature to a standard, out-of-the-box capability for the browser's full user base.
