294093 - Modal javascript alerts prevent closing Firefox and force switching between tabs

Status: RESOLVED DUPLICATE of bug 61098

(Firefox :: General, defect)

Description

[david]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3

Note: Create a new instance of the Firefox process if you value your opened
web-pages:

If you go to the webpage: http://home.comcast.net/~wolfand/ and get stuck in the
Alert loop.

You'll notice that the loop is never ending and that you cannot close Firefox
without killing it (via any chosen method, Mine's the Three-Fingered-Salute)
this is due to the modal behaviour of the popups.

If, however, you Google for "most annoying webpage" (
http://www.google.com/search?hl=en&q=most+annoying+webpage&btnG=Google+Search )
and open the 3rd link (the one I mentioned earlier) in a new tab, the modal
alerts will cause FF to switch between the Google and Comcast tabs without user
interaction.

Reproducible: Always

Steps to Reproduce:
See Details
Actual Results:  
I could only kill Firefox to close it

Expected Results:  
a) Javascript alerts(); and prompts(); shouldn't be modal
b) popups should be linked to their parent tab, not the parent "main window"

well-known DOS, no need for security flag.

I'm sure there are bugs on both potential UI changes, particularly the tab-modal
vs. window- or application- modal.
