Details

User-Agent:       Mozilla/5.0 (Windows NT 6.1) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/11.0.696.44 Safari/534.24
Build Identifier: 4.0

Using this code: <body onresize="alert(1)">

Firefox 4.0 will load the page well, but it will just hang upon resizing the window, showing a black screen, and no alert window showing.

Firefox 3.5 will work perfectly, showing the alert window box.

I suspect that this is due to the new kind of alert box being shown by Firefox 4.0.

Reproducible: Always

Steps to Reproduce:
1.Run a page containing <body onresize="alert(1)">
2.Resize the browser
Actual Results:  
Black screen, unable to proceed

Expected Results:  
A dialog box should be shown
Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

Yes, it occurs in Safe Mode, but not in Firefox 3.5

It's not always showing a black screen... it's more like it hanged/looped? that causes it not to render properly
