300287 - Permit plugins to interact with user

Status: RESOLVED WORKSFORME

(Firefox :: General, enhancement)

Description

[IU]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b3) Gecko/20050710 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b3) Gecko/20050710 Firefox/1.0+

Please permit plugins to interact with user.

Firefox routinely hangs when a plugin - routinely QuickTime - is waiting for a
response from a user.  Firefox prevents the dialog from being visible, thus a
response cannot be provided, and Firefox remains unresponsive and must be
forcefully terminated.

In the past I have noticed this problem even with some of Firefox's own dialogs
hanging the browser.


Reproducible: Always

Steps to Reproduce:
1. Install QuickTime 6.5.2, but accept only the default addons 
2. Visit http://www.hummingbirds.net/midi/midi.html
3. Click on one of the MIDI links under "Organ:"
4. Firefox should have hung by now.
5. Try the same link in Internet Explorer.  Notice that you DO get a QuickTime
prompt to install some additional modules.

Actual Results:  
Firefox does not allow visibility and user interaction with plugin-generated
prompts.


Expected Results:  
Behavior should be similar to that of IE, in that the prompt should be visible
and permit user interaction.


I realize that many problems related to this shortcoming have been reported
before.  Therefore I am reporting this as an enhancement request.  If the
developers support this, many of the related bug reports should eventually stop.
