What stops Firefox from rendering a page

I'm currently facing 开发者_运维百科the problem that the server delivers a page with valid xhtml (transitional) but Firefox (3.x) refuses to render it every now and then. Reloading the page (F5) shows the rendered contents as supposed.

Looking it up in Firebug shows that the server delivered everything and that the html-header als "arrived" ... but it seems that the doesn't have any contents - also not even the onload-event is triggered (if something is defined there) - so it seems that Firefox never really "tries" to process the .

Several others also reported this issue, therefore I assume that it's not a local bug.

Are there any known issues in regards to Firefox which could be related somehow?

Maybe its dynamic js caused it.

$.getScript('http://v2.jiathis.com/code/jia.js', function() {
    alert(1);
});

The code above will stop Firefox 3.x from rendering.
