Is that image scaled up/down as that can be a possible cause ?

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?

The images are scaled via transform.

Thank you very much for your help We resized the images and it worked as you predicted You can see the result here: https://programmaticdemo.online/Mozilla-blurry2/


The issue is that we are preparing so many sizes that it is inconvenient to create for each one of them a specific image size. The question is why Chrome result is different and is there a way to achieve the same in Firefox without creating so many variation of the same image ?

Thank you

Firefox doesn't always do a good job with scaling images and results may vary. In this case it looks rather bad and I don't know if this is about using transform as it doesn't look that bad if I zoom the image in a tab.

Maybe file a bug report if you can attach a test page that clearly shows the problem.
