I do not have a problem rendering that page in Firefox 25.0 on Debian. However based on your crash report, it looks like Firefox is crashing when it tries to render a layer in its graphics engine. Since graphics rendering in Firefox is highly platform-specific, it makes sense that you are having a problem on OS X which others do not encounter in the same version of Firefox on Windows. Taking into account virtorio's claim that he was having the same problem yesterday but not today, his conjecture that a banner ad is triggering the bug seems plausible. There are a couple of other people using Firefox 26 Beta on OS X who are not having the same issue, so it is possible that the bug is fixed in that release.
If you are still experiencing this problem and would like to stick with the Firefox stable channel, disabling layers acceleration might avoid the bug. I don't own a Mac anymore so I can't test this conjecture, but it seems like a likely work-around based on your crash report. To disable layers acceleration, navigate to "about:config", set "layers.acceleration.disabled" to "true", and restart Firefox.
