296780 - Cannot show a blocked popup if the string 'dom.popup_allowed_events' is empty

Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[atzaus]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050601 Firefox/1.0+ (BlueFyre)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050601 Firefox/1.0+

If all events are removed from the string 'dom.popup_allowed_events', FireFox
blocks all popups which is very useful now as many sites have found methods to
circumvent the popup blocker. But if you want to show a blocked popup by
clicking "Show <POPUP_URL>" the popup isn't displayed, which should be the case,
to allow users to temporarily show some popups on such sites without adding
these sites to the white list.

Reproducible: Always

Steps to Reproduce:
1. Empty the string 'dom.popup_allowed_events' in about:config
2. Go to http://popuptest.com/popuptest4.html
3. Click "Mouseover PopUp"
4. Click the popup icon in the status bar and click Show
"http://www.popuptest.com/popup9.html"

Actual Results:  
The popup is not displayed

Expected Results:  
The popup should have been displayed as requested by the user

This is invalid, as mentioned on IRC. That pref is not meant to be changed, the
fact that doing so causes things to malfunction is not a bug.
