Status: RESOLVED DUPLICATE of bug 194404

(Firefox :: General, defect)

Description

[dave]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040614 Firefox/0.9
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040614 Firefox/0.9

Compatibility problem with IE. Can not provide URL as this is an Internal
Enterprise software package (Magic Helpdesk Enterprise version). 

A login pop up window should appear when you click on the link. The page
appears, but the window with the login information does not. Because there is no
way to log on, can not go further.

I enabled and disabled pop-up blocking. Both give same results.

Checked all settings, installed Mozilla 1.7 as well and tried it through there.
Same error message appears. Tried downloading latest Java stuff from sun, same
thing happens. 

Works fine under IE.

When I go to the Javascript console it shows the following error: 
Error: window.showModalDialog is not a function
Source File: http://ldbnts27/servicedesk/
Line: 85

It does NOT crash, just can not proceed further.

Search through Bugzilla did not show any problems that seem to match.

I suspect you will not be able to reproduce the problem due to the software
being crazily expensive, but it does occur all the time and we were looking to
migrate about 500 PCs off IE due to security reasons.
 

  

Reproducible: Always
Steps to Reproduce:
1.Open up Firefox
2.Enter URL
3.

Actual Results:  
Background window opens up fine, but the pop up that prompts for Login Name and
Password does not show.

Can not proceed further. 

It does NOT crash.

Expected Results:  
Pop up window should've appeared prompting for user id and password. Once
entered it should've loaded up the MAGIC helpdesk application.
