Firefox suddenly stops showing background


If you look at this page: http://home.fnal.gov/~cplager/log/0909/log.html

You'll see that just near the bottom, Firefox 19 stops showing the background. This bug can mean that for certain pages, it becomes unreadable.

Please fix this bug soon.

This is likely this bug on Windows (works for me on Linux).

As a temporary workaround, assign a suitable background color in addition to the image. For example:

body {
    background-color: #eee;
    background-image: url("rough-grey.jpg");
    font-family: "Trebuchet MS",sans-serif;

If that isn't your site, never mind!

Question owner

@Cor-el: This wasn't a problem for Firefox 18. Is there an ETA to getting this fixed?

@jscher2000: I've seen this on both my pages and others. The page I sent you was my page and I put in your temporary fix for now.

Hi Reitman, this thread is about background images cutting off after a particular length. Do you have this specific problem (please give an example URL), or do you have the problem you posted about in this thread: Draw bug on background-image inline-css when content is created dynamically. To prevent confusion, let's keep the two problems in separate discussions.
