Description

[[e-mail]]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0) Gecko/20100101 Firefox/12.0
Build ID: 20120420145725

Steps to reproduce:

Opened web page http://www.gupetition.org/ on Windows 7 64 bit laptop running Firefox 12.


Actual results:

The body of the web page does not display. This happens to other sites also. It works fine in Internet Explorer 9. I inspected the element and clicked on the HTTP button. All of the content is there, it simply doesn't display.


Expected results:

The body text should have displayed.

I see this on Mac as well using both the latest nightly and latest Beta. The same site does show the rest of the content on Chrome.

The main content is off-screen on the right for some reason, when I view that page.

It's something to do with the floating header not being cleared. If you open the Web console (Ctrl+Shift+K) on that page and enter

document.getElementById("main").style.clear="both"

that seems to fix it. I don't know why it displays differently in Firefox than other browsers though.
