540151 - DoS by alert() modal

Status: RESOLVED DUPLICATE of bug 61098

(Firefox :: General, defect)

Description

[Gravis]

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.6) Gecko/20091216 Iceweasel/3.5.6 (like Firefox/3.5.6; Debian-3.5.6-1)
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.6) Gecko/20091216 Iceweasel/3.5.6 (like Firefox/3.5.6; Debian-3.5.6-1)

a modal dialog disables interfacing with everything except the dialog so when an alert() is put into an infinite loop, you are stuck until you kill the application.

someone unfixed this problem from a previous version.  -_-;

Reproducible: Always

Steps to Reproduce:
1. go to http://adaptivetime.com/itsatrap.html
2. click the "It's perfectly safe to click this button." button
3. panic
Actual Results:  
an alert box with "Are you having a flashback to 1998 yet?" shows up and you cannot access any other part of the GUI to navigate away from the page.  clicking "OK" only leads to the same alert message box returning before you can do anything.  YOU ARE STUCK!

Expected Results:  
an alert box with "Are you having a flashback to 1998 yet?" shows up and you cannot access other parts of the GUI to navigate away from the page.

this is the most rudimentary DoS attack that _needs_ to be fixed.
