Funny you mention this -- I don't think this is due to malicious code, because
I have had a similar problem in IceWeasel, a crash when I closed a
popped-out google chat window.  I haven't seen a repeat of this so I don't
know if it was a fluke, but it does seem that under certain circumstances
which I can't yet elaborate, closing a popup will crash the browser.



Okay - the web browser might not itself, contain malicious code, but, when attempting to close a tab, an unauthorised pop-up displays, and says something like "Are you sure you want to close this window? Click <whatever button> (in the unauthorised popup) to confirm/continue", that, to me, is a vulnerability/security risk, created by the browser's inability to block unwanted pop-ups.

As  a single example of this, open
http://www.truthaboutabs.com/get-ripped-abs.html , then, try to close it, by simply clicking on the box with a cross in it, that is to close either a tab or a browser window.

Unwanted pop-up appears! Malicious code!

And, that the web browser does not allow me to mark and copy the text that is displayed in the unrequested popup window, is a concern in itself, as it is clearly allowing an external web site to take control of the system, in preventing me from marking and copying the text in the popup window.

How are we to know whether these things contain malicious code that is written to spread malicious code or otherwise take control of the system?

We should not have to go out to a console session, and use "ps -ax | grep iceape", then "kill -9 <each pid showing iceape>", and kill all sessions of iceape, just to close a single, malicious tab, that is allowed by security breaches in the mozilla/firefox/iceape/iceweasel software.

It is, to me, the web browser saying to the world, "Hey, everyone! here is some idiot's computer for you to gain unauthorised entry to and control over!".

If the web browser is unable to block unwanted pop-ups, then we should not be misled by the browser, into thinking that it will block unwanted pop-ups that are a threat to system security.

That in itself, is particularly disturbing - that we are misled by settings in the browser, that are supposed to protect us, that actually provide no protection.

is that indicating that the web browser, does in fact contain malicious code, when it m,isleads the user into wrongly believeing that the user is protected from a particular security threat?

That, I think, is a fair question.

"Here is this special, new, armour plating compund, that will stop all bullet and armour-piercing projectiles. Just because it is actually just a roll of cling-wrap for food covering, does not mean that it will not protect your household from drive-by shootings."

That is the nature of the option "Block unrequested popup windows", being an option to be set, that simply does not work.

Whether that failing, is what causes the other instabilities (leading to the blank "untitled windows"), is something for the software maintainers to investigate, but, the software is insecure and deceptive, in falsely pretending to "Block unrequested popup windows".
