How can you disable image smoothing if firefox?

Whenever I zoom into images in Firefox (example), the image smoothing makes them look blurry, especially on low resolution images. Is there any way to disable image smoothing of Firefox?

Well, hmm, there isn't a built-in setting for this but if there happens to be a style rule in the page to switch from bilinear scaling ("auto") to nearest neighbor scaling ("crisp-edges") then you'll get a different result. As an example, see the attachment.

The style rule for that is:

img {
  image-rendering: crisp-edges !important;
}

You can use an extension like Stylus to inject that change into every page, but I don't know whether you want it on every page or only selected pages. ??

I put the code into stylus, and image smoothing is now disabled. I don't know how to make it inject the code in every page, so I just made it apply to any url that starts with "http". All pages have no image smoothing now, thanks!
