EDIT: Today I dug a bit more and found that dom.image-lazy-loading.enabled preference has been removed and saw this comment on a related thread:

FWIW, it should still be possible to effectively turn off lazy loading by setting dom.image-lazy-loading.root-margin.* to a big number.

Which I tried (value 100000) and it works!

Hi, I have a slow connection and for pages with lot of images it's very convenient to open the page and wait for all the images to load before watching them.

I have dom.image-lazy-loading.enabled set to false but I have found webs where it doesn't work, like with Behance galleries. I see the loading="lazy" attribute on the img tags, but they don't load until I scroll down to them.

Does anyone know if I'm missing something or if there is any way to debug it further?

There are also pages (like this one) in where I don't see the loading="lazy" attribute but I see a lazy-images.js file on the Debugger file list, data-lazy-src attributes in img elements and other img elements with loading="lazy" inside noscript tags. I understand that the dom.image-lazy-loading.enabled setting may not work with custom lazy loading implementations.

Does anyone know of any solution for these cases?

EDIT: I've also tried LazyLoadify add-on with no luck.

Thanks!
