User-Agent:       Mozilla/5.0 (X11; U; Linux i686; pt-BR; rv:1.9.2.3) Gecko/20100423 Ubuntu/10.04 (lucid) Firefox/3.6.3

When accessing a site that has an script with an infinite loop, Firefox stops to respond.

Example:

<html>
<script>
for (;;)
alert("Hello, world!")
</script>
</html>

When Firefox loads a page like this, there is no option to stop the script (like other browsers: Opera and Chrome). The suggestion is to add a checkbox in the alert window like: "Block script on this page".

Reproducible: Always

Steps to Reproduce:
1. Opens a site with a infinite loop (like this one: http://programacaoemjava.blogspot.com/2010/06/infinite-loop.html)
Actual Results:  
You can not stop the script unless you kill Firefox' process (which turns Firefox unusable).

Expected Results:  
There should be an option to block scripts on the page.
