Could you create a stacktrace for the hang ?

It also hangs for me on new profile.
Using builtin Profile, I see most of the time is spent under (about 96.7%) in:

nsCSSRendering::PaintGradient ----> gfxContext::Fill

Same URL does not hang on Chromium 26 dev.

Disable background-image( i.e., the following userContent.css helps)

#article_top .article_image div .screen {
background-image:none !important;
}

So, I think this is related to  Bug 823147 .
The offending css is as follow:

#article_top .article_image div .screen { background-color: white; background-image: radial-gradient(rgb(102, 51, 153) 15%, transparent 16%), radial-gradient(rgb(102, 51, 153) 15%, transparent 16%), none; background-repeat: repeat, repeat, repeat; background-attachment: scroll, scroll, scroll; background-clip: border-box, border-box, border-box; background-origin: padding-box, padding-box, padding-box; background-position: 0px 0px, 18px 11px; background-size: 7px 7px; }

Marking as duplicate since we already have several bugs for psfk.com gradients.

Bug 826422 will improve the HWA off case.
