288383 - Firefox reports that a popup was blocked, but fails to block a potentially harmful popup

Status: RESOLVED DUPLICATE of bug 176079

(Firefox :: Security, defect)

Description

[Chris Walsh]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.7.6) Gecko/20050321 Firefox/1.0.2
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.7.6) Gecko/20050321 Firefox/1.0.2

When right-clicking on a link to open it into a new tab, Firefox reports that a
popup had been blocked, but it gets through anyway.  The popup reads "WARNING,
You may have critical errors on your PC..."  It seems to happen at least once a
day when visiting the site, www.tvtome.com, and using the navigation technique
described.  This does not happen each time, mainly once daily.  The problem has
been noticed in v1.0 to v1.02.  This does not happen in IE6.  I have a
screenshot if desired.  I have scanned for spyware and it comes back negative.

Reproducible: Sometimes

Steps to Reproduce:
1. Navigate to the site: http://www.tvtome.com
2. In the search box in the upper right corner, type "CSI" and search
3. In the program links, right-click on "CSI" and choose to open in a new tab.

Actual Results:  
A long rectangular popup will appear, always with the same message "WARNING, You
may have critical errors on your PC..."

Expected Results:  
Blocked the popup

I have flagged this as a potential security issue.
