Description

[Eric]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3

When developing an extension and extending the nsIContentPolicy, if you block a regular url say google.com.  It works just fine.  However if you click an external link in say word, an email program, or a custom program then the link is blocked but firefox opens a new blank tab, and a new blank window.   This only happens if the link is blocked.  If the link is not blocked the page loads normally.

Reproducible: Always

Steps to Reproduce:
1.Install an extension that blocks web pages using the nsIContentPolicy interface.
2.Click on a blocked link in an external program
3.Firefox will open a new blank tab, and new blank window.
Actual Results:  
Firefox will open a new blank tab, and new blank window.

Expected Results:  
Firefox will open a new blank tab, and new blank window.

Not opened a new tab, and not opened a new window.
