Iframe lazyloading

Hi @bluisier,

it seems to work fine in Firefox. Do you have the option for native lazy loading enabled (should be, because the loading="lazy" is there)? If so, could you try to disable it and see if that helps?

Best,

Hi @florianbrinkmann ,

THANK YOU!!! That did the trick. I disabled native lazy loading and now I don’t have all the Iframe scripts loading on chrome anymore. Do you know why this was hapenning?

Hi @bluisier,

great to hear that! ?? And thanks for your donation ? I will mark this as resolved.

To your question: When native lazy loading is used, browsers that support native lazy loading (like Chrome) decide when to load a resource, and not the lazysizes script.

And the result is that some browsers load things that are far away from the visible area, and as far as I know, that is nothing that can currently be modified. In this post (https://addyosmani.com/blog/lazy-loading/) I found a link to chromium code (https://source.chromium.org/chromium/chromium/src/+/master:third_party/blink/renderer/core/frame/settings.json5;drc=e8f3cf0bbe085fee0d1b468e84395aad3ebb2cad;l=937-1003) that says iFrames are loaded at least 4000px before visible.

Best,
Florian
