Because of a bug in the Windows version of Firefox 22 and 23, your browser may crash while reading Float32/Float64 NaN values ("Not a Number").
Unfortunately this problem is not circumvented. I've already submitted a bug report to Mozilla, directly after the release of Firefox 22, and they've marked it as critical "Security-Sensitive Core Bug", but it seems their priority is to change the browsers icon, than to fix bugs, so it still occurs in Firefox 23.
Till it is fixed, I recommend to use Google Chrome, Apple Safari, Microsoft Internet Explorer, Firefox 21 or the Linux or MacOS version of Firefox 22+.
