jpegxl.info - design is broken

URL: https://jpegxl.info/test-page/

Browser / Version: Firefox 129.0 Operating System: Linux Tested Another Browser: Yes Other

Problem type: Design is broken Description: Images not loaded Steps to Reproduce: The JPEG XL images are visible when JPEG XL‌ support is enabled (Firefox Nightly, image.jxl.enabled set to true). However, transparency and animations aren't properly supported, as shown in the the JPEG XL Test Page for the dice example and the rotating geometric figure at the bottom of the page. All the images work correctly in other JPEG XL supporting browsers, such as Otter with QtWebKit and the jxl format whitelisted.

We appreciate your report. I was not able to reproduce the issue following the steps to reproduce regardless of the pref setting:

Tested with:

Browser / Version: Firefox Nightly 129.0a1 (2024-06-26) (64-bit) Operating System: Ubuntu 22.4 LTS x64

Suggestion: Try clearing cache/data/cookies, disabling add-ons and Ad-blocker (if available) and extensions or use a clean profile, and check again? If there are any changes made to the default settings of the browser (e.g. in about:config) please revert to the default settings and try again. Also, have the required cookies been accepted for this page?

Hi @softvision-raul-bucata, from your screenshot it would seem that JPEGL XL support is not enabled in your FF nightly, since the jxl image shows the alt text instead of a rendering of the image, which probably means that image.jxl.enabled is not set to true in about:config. Could you please double-check?
