566179 - Cmd+Tab while "Bookmarks backup filename" dialog is open causes Firefox to hang

Status: RESOLVED INACTIVE

(Firefox :: Bookmarks & History, defect)

Description

[negativedouble]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-GB; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-GB; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3

Firefox is left in a state where none of the open dialogs can be dismissed if Cmd+Tab is used to switch to another application then back again while the "Bookmarks backup filename" dialog is open.

Reproducible: Always

Steps to Reproduce:
1. From the application menu, choose Bookmarks -> "Organise Bookmarks...".
2. In the Library dialog, from the pull-down menu with the star icon, choose "Backup...".
3. While the "Bookmarks backup filename" dialog is open, switch focus to another application (Cmd+Tab).
4. Switch focus back to Firefox (Cmd+Tab).
Actual Results:  
The Library dialog shows the following pop-up:

"
Warning: Unresponsive script

A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

Script: chrome://global/content/bindings/general.xml:0

Continue / Stop script
"

The "Unresponsive script" warning pop-up can't be dismissed because the "Bookmarks backup filename" child dialog is still active, but the "Bookmarks backup filename" dialog can't be closed because its Cancel and Save buttons have become unresponsive.

Firefox has to be killed with "Force Quit...".

Expected Results:  
The "Unresponsive script" dialog should not be parented to the "Library" dialog when the "Bookmarks backup filename" dialog is open.

Able to reproduce the issue causing Firefox to hang. After selecting "Backup" from Organise Bookmarks, Switching focus to another application (cmd+tab) hangs the browser with an error dialog.

eh, the filepicker dialog causes the main loop to freeze, there is no easy solution to that on bookmarks side.
