1062520 - Permission Window doesn't notice when all permissions are removed

Status: NEW

(Toolkit :: Preferences, defect)

Description

[Mark Hammond [:markh] [:mhammond]]

permissions.xul/.js doesn't have an observer for the notification sent when nsIPermissionManager::RemoveAll() is called ("cleared"), thus it doesn't notice when permissions are removed this way.

STR:
* Open any dialog using permissions.xul with permissions listed.
* Select "Clear recent history", ensure Site Preferences is selected, and select "remove all".

Expected:
* The open dialog should reflect the permissions were removed.

Actual:
* The open dialog doesn't change.  You must close the dialog and re-open it to reflect the removed permissions.

This is probably a low priority as the chance the users will clear all permissions externally while the dialog is open seems low, but YMMV...
