serfing, & popunder... I close them...
it opens new window without controls...
Try to close window by its [X] but active dialog is in loop... 
Malicious page try to "install video codec" absolutely mandatory
(bug-loop, or malicious mistification, fake dialogs, like native install?), 
& loop: install?>no> ~ ... not installed, must be for video blabla>NO>install? etc
I see, that it's not a codec, but horse ) (?)
Cannot use any controls to kill...

And worse, cannot close only that window - task manager do not show windows of FFox personal ID etc - only 1 process, 1 PID...
how can I kill it without kill all?
[X] in each window must be absolutely mandatory/unlockable and kill any open dialogs etc... only ask - yes/no, and kill it... imho... serious sequrity problem, users often like to "install codecs for see it" 
may be, some troyans that I find, use this method?

bad english, sorry!

opens not killable window with codec install dialog loop

Expected Results:  
aaa...
possibilities to kill any windows(or tabs) of FF at my wish at any time, with any dialogs, etc... without any deadlocks, by [X] and only short dialog yes/no/really?
but not all windows/tabs of FF... imho - it's a crash...

The first "window" is no window and if you click "x" you are in a JS alert loop.
