796848 - When closing a tab via the tabs tray or Firefox via quit onbeforeunload is not fired

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: General, defect)

Description

[Nicolas FROIDURE]

Attachment: test.html

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.79 Safari/537.4

Steps to reproduce:

Register a function to window.onbeforeunload
Use the menu button, choose Quit
(Did it in Firefox for Andoird Beta but earlier versions are also impacted)


Actual results:

Firefox is not closed, it's just put to the background and going back to the Firefox view shows the unbeforeunload message but it doesn't respond anymore to any action.
The only way to get Firefox back is to kill him.


Expected results:

Firefox should show the onbeforeunload dialog before closing.

Moving back to Android product since I think this is Android-specific. In particular, when the user selects Quit from the menu we change sLaunchState to LaunchState.GeckoExiting, which causes us to queue any further events sent to gecko. Gecko, meanwhile, is probably expecting the UI to continue to be responsive; java and gecko are out of sync and this causes the observed behaviour.
