User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:50.0) Gecko/20100101 Firefox/50.0 Build ID: 20161209093710 Steps to reproduce: Browse to facebook, and compare the quality of images shown in my feed to that seen in Chrome. Device is a Nexus 5X, OS version 7.0. Actual results: Images is Firefox are noticeably blurrier than in Chrome. It's not as obvious in some images as others, but it's always present. Expected results: Images should be sharp as they are in Chrome.

I've attached screenshots in both browsers of the same web view to illustrate the problem. I should also mention that I tried setting image.high_quality_downscaling.enabled=false as I saw mentioned in another bug, 920957. It didn't make any detectable difference.

Actually, if this is specific to Facebook, they might be sending Firefox lower-resolution images and Chrome higher-resolution images. If you're able to use the Firefox devtools you can check the size of the images in both browsers.
My guess is that this is webcompat and that Facebook is sending higher quality images (maybe in the webp format).
