(Firefox :: Settings UI, enhancement)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5a) Gecko/20030728 Mozilla Firebird/0.6.1

Webpages can prevent the context menu appearing when right-clicking, by changing
the document.oncontextmenu event handler. A Javascript preference should be
available to prevent pages overriding the default handler.

Reproducible: Always

Steps to Reproduce:
1. Create a page with the following code in the BODY:
  <script>
      document.oncontextmenu=new Function("return false")
  </script>
2. The context menu no longer appears when right-clicking on the page.


Actual Results:  
The context menu does not appear when right-clicking. 

Expected Results:  
The user should be able to control whether a page can do this, through a
Javascript preference: "Allow pages to control context (right-click) menu."
