150301 - Pop-Up Blocker doesn't always work.

Status: VERIFIED DUPLICATE of bug 152167

(SeaMonkey :: Preferences, defect)

Description

[Robert Zaichkowski]

Recently, when I downloaded Mozilla 1.0, I found this option to block pop-ups. 
This would be done by going into the Preferences, then Advanced, then Scripts &
Windows.  On there, there is an option to show unrequested windows.  Normally,
this option is on.  I thought by deselecting this option would block all pop-ups
available on the Internet.  However, when I accessed the URL indicated to log
into my e-mail account, there appears to be a problem.  Normally, when logging
into a E-mail account at http://www.mail.com, a pop-up saying "A Great Deal For
You" comes up.  Mozilla managed to block that.  However; when I selected some of
the messages and deleted them, or decided to empty the trash bin; the pop-ups
weren't blocked.  I'll display an attachment to show the proof.  Actually, it is
a pop-up controlled by some JavaScript operation since when I highlighted over
the Delete button at Mail.com, it had JavaScript something at the Status Bar. 
The same goes for some of the security sites such as http://www.cracks.am and a
few others, but the pop-ups on security and warez sites aren't JavaScript. 
Therefore, I would recommend fixing up this pop-up issue by Mozilla 1.0.2 or
Mozilla 1.1.

please save the mail.com page as a "web page, complete", zip up all the files
involved, and attach to this bug....

What are the steps to reproduce on http://www.cracks.am/main.html?

Those popups (mail.com) are impossible to block in a generic way, they are
launched in response to a click from the user, so the only valid solution would
be to block popups by site (that bug already exists)

Attachment: Mail.com Complete site.

I just attached the Mail.com site as recommended.  For the site
http://www.cracks.am, I just typed that site in the Address Bar.  Eventually,
after a few seconds, the extra pop-up windows will appear.  The same will go
for many other security and warez sites.

http://www.cracks.am uses onmouseover pop-ups.  This is why I said pop-up
blocking should use a whitelist of events, not a blacklist...

The problem at cracks.am is bug 152167.  It sounds like the problem at mail.com
can't be fixed without also blocking all legit pop-ups.
