Poor rendering of Facebook Timeline cover-photo in Firefox 9.0.1

Greetings,

The Facebook Timeline cover-photo seems to render very poorly in Firefox. The image looks blurry. The problem has been there since coverting my profile, and persists with Firefox 9.0.1. The image is made with the right dimensions (850x315px). I've tried uploading jpg/gif/png, interlaced/noninterlaced (...but Facebook converts to jpg). No problems with other browsers. If I copy the image location and load the image in a new tab it looks just fine (...which causes me to believe that the problem is with how Firefox handles the CSS?). Tried uninstalling/reinstalling Firefox.. Tried disabling color management (about:config). Did View>>Zoom>>Reset.

Any help appreciated. Thank you.

You can check in Tools > Page Info > Media if images are resized.
Also make sure that you are not zooming pages, so reset the page zoom on pages that cause problems.

Thank you cor-el, for your fast reply! It was indeed scaled. 850px × 315px (scaled to 851px × 315px) Now why Firefox scales it, I do not know. A temporary fix for me was to make the image 851px × 315px before uploading. Now it looks good in all browsers.

Technically my problem is solved by this work-around, but I'll leave this open for a day or so, hoping that someone might adress the core issue.

Thanks again.

You're welcome.

Firefox will only scale images if there are dimensions specified in the image code to do that, so check the code to see if there is a height and width specified, either in the image tag or via CSS.
