Status: RESOLVED DUPLICATE of bug 529655

(Firefox :: General, defect)

Description

[Alan Baxter]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2) Gecko/20100105 Firefox/3.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2) Gecko/20100105 Firefox/3.6

Clicking Options for an extension sometimes causes the Add-ons Manager window to freeze while "No chrome package registered for chrome" is displayed in the Error Console.  The Add-ons Manager no longer responds to mouse clicks or key presses.  It can be eliminated only by killing Firefox from the XP Task Manager.

Reproducible: Always

Steps to Reproduce:
1. Create a new profile with Fx 3.6 RC1
2. Install BlockSite 0.7.2 from https://addons.mozilla.org/en-US/firefox/addon/57211
3. Open the Add-ons Manager with Tools > Add-ons > Extensions
4. Click on the BlockSite Options button
Actual Results:  
No Options dialog pops up.
The Add-ons Manager cannot be closed.  Pressing Esc or Alt-F4 has no effect.  Clicking the close button has no effect.
The Error Console displays "No chrome package registered for chrome://blocksite/content/BlockSitePrefs.xul"
The Firefox browser window can be closed with File > Exit, but the Add-ons Manager persists and firefox.exe remains in the Task Manager.  I had to kill Firefox from the Task Manager to kill the frozen Add-ons window.

Expected Results:  
The BlockSite Preferences dialog pops up.
The dialog can be dismissed by pressing Esc or Alt-F4 or by clicking OK, Cancel, or the dialog's close button.
The Add-on Manager can be then be closed.

Problem also exists in
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2pre) Gecko/20100112 Namoroka/3.6pre
and
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.3a1pre) Gecko/20100112 Minefield/3.7a1pre

Problem does not exist in Fx 3.5.7.

I confirmed on Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2pre) Gecko/20100114 Namoroka/3.6pre ID:20100114050231

This expansion does not include chrome.manifest.
But optionsURL is defined in install.rdf.

What is happening here: extension manager tries to open extension options as a modal dialog. This fails (optionsURL given is wrong) - but we still end up with a modal dialog, a transparent one. For the user it looks like the extension manager window is broken. I don't think this can be really fixed on the extension manager's side (even if the dialog is opened in non-modal mode, we still end up with a transparent window that we certainly don't want). So this is a core bug, this window shouldn't be opened in the first place.
