312786 - Alert box flood causes data loss by making entire browser window inaccessible

Status: RESOLVED DUPLICATE of bug 61098

(Firefox :: General, defect)

Description

[Lupin.wp]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Firefox/1.0.7 (Debian package 1.0.7-1)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Firefox/1.0.7 (Debian package 1.0.7-1)

If you have a window with several tabs and a poorly written script produces
alert boxes in an infinite loop, then you can't access the tabs and so lose all
your data.

Reproducible: Always

Steps to Reproduce:
1. Open a page in a tab, and create a new tab.
2. Type javascript:while(1){alert('gah')} in the address bar and hit enter

Actual Results:  
The alert boxes pop up, and you can't switch back to the first tab or interact
with the browser window in any way.

Expected Results:  
The alert boxes should only be modal for the tab from which they were called;
browsing in other tabs should not be affected. Moreover, it should be possible
to kill the tab from which the script originated, thus breaking the loop.
