This is a regression which goes a few months back. It worked fine before, but a
while ago it got broken.
Reproducible: Always.
Steps to reproduce:
1. Clear browser cache.
2. Right click on this link: http://www.mozillazine.org/ and Open it in New Tab.
3. Wait for page to load without looking at it. Give it a minute or so.
4. Bring the tab to front.
Actual results: The sky and grass backgrounds are missing and start loading only
when you view the page.
Expected results: The whole page finishes loading by the time you view it.
Same thing happens if backgrounds are outside of viewport. They start loading
only when you scroll and bring them into view.
Same happens for :hover backgrounds, they don't load until mouse hovers over
element.

I reopened bug 121913
stylesheets do load for me, it's the CSS backgrounds that don't load right away.

Apparently not only CSS, but <body background="image.jpg"> is also affected.
Summary: CSS background images are not downloaded until the page is viewed → background images are not downloaded until the page is viewed

Additionally in order to reproduce please select "Middle click or control-click
in a Web page" inside Preferences->Navigator->Tabbed Browsing prior to
performing the above steps.
Unlike in Windows, on Linux backgrounds do load if they are inside the viewport.
Outside the viewport, however, they still don't start loading untill they are
scrolled into view.
On Windows, in addition to that they are not loaded when inside the viewport
*and* the viewport is in the background. Start loading only when the viewport is
brought to front.
