www.samsung.com - Some images are not rendered

URL: https://www.samsung.com/in/smartphones/galaxy-s23/

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

Problem type: Something else
Description: There are animated images which do not show up in Firefox.
Steps to Reproduce:
On the back of this thread here: https://forum.garudalinux.org/t/firefox-doesnt-render-some-websites-properly/26529

I have attempted to get the website to show up in Firefox. I have gone through a litany of interventions to get the website to display in Firefox, but it does not.
• Enabled Wayland mode
• Disabled Wayland mode (X11)
• Enabled hardware acceleration in the browser
• Ran the browser in safe mode (disables all extensions and graphics acceleration)
• Installed Firefox ESR - issue persists
• Installed Firefox Developer Edition - issue persists

In all Chrome-based browsers and in Firefox on Windows, the website displays fine. Only Firefox on Linux has an issue (multiple Linux distros were tested, including Arch-based, Debian-based, Linux Mint, and Fedora).

The attached screenshot shows Firefox on the left, and Vivaldi on the right. In Vivaldi, the images are shown and the animations work correctly. In Firefox, the space on the page is just blank.

@BluishHumility Thanks for the report. What I would do usually to test this kind of issue, is:

1. Type about:profiles in the url bar.
2. Choose Create a new profile.
3. Call it deleteme or anything you please.
4. Then start it. (this way you will be sure that nothing is interfering, no ghost caching etc.)
5. Test.

Hi @softvision-raul-bucata, apologies for the lengthy delay in response--somehow I missed the notification that there was activity in the thread.

I can confirm creating a new profile as you have described does not have an impact on the issue. The page still loads in its "broken" state, with none of the animated images displayed.

I have also brought up this page on the back of a fresh Arch installation with no browsing history whatsoever, and the page is still broken the same way.

Others in the thread linked above have tested on different machines, Linux installations, and versions of Firefox (including Librewolf and Firedragon) and the page is always broken on Linux. It seems to be something specific to the webpage, but then again that is an armchair diagnosis.

Please let me know if there is any additional troubleshooting we can do that would be helpful.

I was able to reproduce the issue:

Tested with:

Browser / Version: Firefox Release 110.0.1 (64-bit)/ Firefox Nightly 112.0a1 (2023-03-02) (64-bit)/Chrome Version 110.0.5481.178 (Official Build) (64-bit)

Operating System: Ubuntu 22.4 LTS x64

Notes:

1. Reproducible regardless of the status of ETP.
2. Reproducible on the latest build of Firefox Nightly and Release.
3. Works as expected using Chrome.

Moving this to NeedsDiagnosis for further investigations.

We've since added an intervention to Firefox to work around this issue, and it should be fixed (the link works for me on Linux now).
