After displaying a JavaScript alert box using the function "alert()", the interface in the current window freezes. The only remaining working items are the menu, keyboard shortcuts (which I presume are tied to the menu), as well as the "X" button in the tab bar (although the tabs do not work). The webpage continues to function properly. In the "Window" menu in the menu bar, there is a long list of blank windows that seem to be caused by the alert dialog. This only seems to occur when the alert dialog is accessed via a "onmouseover" trigger.

Reproducible: Always

Steps to Reproduce:
1. Create a blank HTML file
2. Create a JavaScript function that uses the "alert()" function.
3. Create an anchor tag that calls the JavaScript function using "onmouseover".
4. Open the HTML file in Firefox and hover your mouse over the link.

Actual Results:  
The interface freezes leaving only the menu, keyboard shortcuts, and "X" button on the tab bar to work. The webpage continues to function. The "Window" menu is also flooded with blank windows.

Expected Results:  
The interface should continue working properly.

I wrote this file to try to reproduce the bug. Everytime you hover over the "Alert!" link, the bug occurs. However, if you click on the "Click to Alert!" button, the bug does not occur.
