I had this bug and fixed it as in comment #11.
This was fine, on a Pentium M Toshiba laptop, using Lubuntu 14.04.
However, after the latest update of Firefox (40.0) Firefox stops loading before the URL-bar appears, and pages can be loaded. Just the main frame appears, with the heading with the name of the start page.
I found the setting " gfx.xrender.enabled" to False is the culprit, so I had to undo this setting.

So: now what should I do?
