+# WebappRT doesn't need these instructions, and they don't necessarily work
+# with it, but it does use a GRE directory that the GRE shares with Firefox,
+# so in order to prevent the instructions from being processed for WebappRT,
+# we need to restrict them to the applications that depend on them, i.e.:
+#
+#   b2g:            {3c2e2abc-06d4-11e1-ac3b-374f68613e61}
+#   browser:        {8de7fcbb-c55c-4fbe-bfc5-fc555c87dbc4}
+#   mobile/android: {aa3c5121-dab2-40e2-81ca-7ea25febc110}
+#   mobile/xul:     {a23983c0-fd0e-11dc-95ff-0800200c9a66}
+#
+# In theory we should do this for all these instructions, but in practice it is
+# sufficient to do it for the app-startup one, and the file is simpler that way.

+<!-- This overlay provides a downloads view that lists both session downloads,
+     using the DownloadsView API, and history downloads, using places queries.
+     The view also implements a command controller and a context menu for
+     managing the downloads list.  In order to use this view:
+     1. Apply this overlay to your window.
+     2. Insert in all the overlay entry-points, namely:
+        <richlistbox id="downloadsRichListBox"/>
+        <commandset id="downloadCommands"/>
+        <menupopup id="downloadsContextMenu"/>
+    3. Make sure your window has the editMenuOverlay overlay applied,
+       because the view implements cmd_copy and cmd_delete.
+    4. Make sure your window has the globalOverlay.js script loaded.
+    5. To initialize the view
+        let view = new DownloadsPlacesView(document.getElementById("downloadsRichListBox"));
+        // This is what the Places Library uses. It could be tweaked a bit as long as the
+        // transition-type is set correctly

+/**
+ * A few words on focus and focusrings
+ *
+ * We do quite a few hacks in the Downloads Panel for focusrings. In fact, we
+ * basically suppress most if not all XUL-level focusrings, and style/draw
+ * them ourselves (using :focus instead of -moz-focusring). There are a few
+ * reasons for this:
+ *
+ * 1) Richlists on OSX don't have focusrings; instead, they are shown as
+ *    selected. This makes for some ambiguity when we have a focused/selected
+ *    item in the list, and the mouse is hovering a completed download (which
+ *    highlights).
+ * 2) Windows doesn't show focusrings until after the first time that tab is

+ * In general, the desired behaviour is to focus the first item after pressing

+ *

+    // handling feeds of that type, but without a content-type differentiation
+    // it is difficult for us to disambiguate.
+    // 
+    // The other problem is that if the user specifies an auto-action handler

+    // generic feed content, the system will prevent them from setting an auto-
+    // handler for other stream types. In those cases, the user will always see
+    // the preview page and have to select a handler. We can guess and show

+ * The panel is initialized based on data given in the js object passed

+ *       @ type (String). Possible values:
+ *         - "bookmark"
+ *           @ loadBookmarkInSidebar - optional, the default state for the
+ *             "Load this bookmark in the sidebar" field.
+ *         - "folder"
+ *           @ URIList (Array of nsIURI objects) - optional, list of uris to
+ *             be bookmarked under the new folder.
+ *         - "livemark"
+ *       @ uri (nsIURI object) - optional, the default uri for the new item.
+ *         The property is not used for the "folder with items" type.
+ *       @ title (String) - optional, the default title for the new item.
+ *       @ description (String) - optional, the default description for the new
+ *         item.

+ *      Notes:
+ *        1) If |uri| is set for a bookmark/livemark item and |title| isn't,
+ *           the dialog will query the history tables for the title associated

+ *        2) The index field of the default insertion point is ignored if
+ *           the folder picker is shown.
+ *     - "edit" - for editing a bookmark item or a folder.
+ *       @ type (String). Possible values:
+ *         - "bookmark"
+ *           @ itemId (Integer) - the id of the bookmark item.
+ *         - "folder" (also applies to livemarks)
+ *           @ itemId (Integer) - the id of the folder.
+ *   @ hiddenRows (Strings array) - optional, list of rows to be hidden
+ *     regardless of the item edited or added by the dialog.
+ *     Possible values:
+ *     - "title"
+ *     - "location"
+ *     - "description"

+ *     - "tags"
+ *     - "loadInSidebar"
+ *     - "feedLocation"
+ *     - "siteLocation"

+/**
+ * Session Storage and Restoration
+ *
+ * Overview
+ * This service reads user's session file at startup, and makes a determination
+ * as to whether the session should be restored. It will restore the session
+ * under the circumstances described below.  If the auto-start Private Browsing
+ * mode is active, however, the session is never restored.
+ *
+ * Crash Detection
+ * The session file stores a session.state property, that
+ * indicates whether the browser is currently running. When the browser shuts
+ * down, the field is changed to "stopped". At startup, this field is read, and
+ * if its value is "running", then it's assumed that the browser had previously
+ * crashed, or at the very least that something bad happened, and that we should
+ * restore the session.
+ *
+ * Forced Restarts
+ * In the event that a restart is required due to application update or extension
+ * installation, set the browser.sessionstore.resume_session_once pref to true,
+ * and the session will be restored the next time the browser starts.
+ *
+ * Always Resume
+ * This service will always resume the session if the integer pref
+ * browser.startup.page is set to 3.

+
+# The removed-files.in file specifies files and directories to be removed during
+# an application update that are not automatically removed by the application
+# update process. The application update process handles the vast majority of
+# file and directory removals automatically so this file should not be used in
+# the vast majority of cases.
+
+# When to use removed-files.in file to remove files and directories:
+# * Files and directories located in the installation's "distribution/" and
+#   "extensions/" directories that were added before Firefox 27. Files and
+#   directories located in these directories were not included in the
+#   application update file removals for a complete update prior to Firefox 27.
+# * Empty directories that were accidentally added to the installation
+#   directory.
+# * Third party files and directories that were added to the installation
+#   directory. Under normal circumstances this should only be done after release
+#   drivers have approved the removal of these third party files.
+
+# If you are not sure whether a file or directory should be removed using the
+# removed-files.in file please contact one of the developers that work on
+# application update.
+
+# Note: the "distribution/" and "browser/extensions/" directories should never
+# be removed recursively since these directories are used by Partner builds and
+# custom installations.
+
+# To specify a file to be removed add the path to the file.
+# * If the file doesn't exist the update will succeed.
+# * If the file exists and can't be removed (e.g. the file is locked) the
+#   update will fail.
+#
+# Example: path/to/file
+
+# To specify a directory to be removed only if it is empty add the path to the
+# directory with a trailing forward slash.
+# * If the directory doesn't exist the update will succeed.
+# * If the directory can't be removed (e.g. the directory is locked, contains
+#   files, etc.) the update will succeed.
+#
+# Example: path/to/dir/
+
+# To specify a directory that should be recursively removed add the path to the
+# directory with a trailing forward slash and "*".
+# * If the directory doesn't exist the update will succeed.
+# * If all of the files the directory contains can be removed but the directory
+#   or a subdirectory can't be removed (e.g. the directory is locked) the update
+#   will succeed.
+# * If a file within the directory can't be removed the update will fail.
+#
+# Example: path/to/dir/*
+
+# Due to Apple Mac OS X packaging requirements files that are in the same
+# directory on other platforms must be located in different directories on
+# Mac OS X. The following defines allow specifying the Mac OS X bundle
+# location which also work on other platforms.

+  Comment duplicated from browser-sets.inc:
+
+  Search Command Key Logic works like this:
+
+  Unix: Ctrl+J (0.8, 0.9 support)
+        Ctrl+K (cross platform binding)
+  Mac:  Cmd+K (cross platform binding)
+        Cmd+Opt+F (platform convention)
+  Win:  Ctrl+K (cross platform binding)
+        Ctrl+E (IE compat)
+
+  We support Ctrl+K on all platforms now and advertise it in the menu since it is
+  our standard - it is a "safe" choice since it is near no harmful keys like "W" as
+  "E" is. People mourning the loss of Ctrl+K for emacs compat can switch their GTK
+  system setting to use emacs emulation, and we should respect it. Focus-Search-Box
+  is a fundamental keybinding and we are maintaining a XP binding so that it is easy
+  for people to switch to Linux.

+     downloads and those of blocked downloads.
+
+     A good rule of thumb is to try to determine the longest string possible
+     that an in-progress download could display, and use that value in ch
+     units.
+
+     For example, in English, a long string would be:
+
+     59 minutes, 59 seconds remaining - 1022 of 1023 KB

+
+     A good rule of thumb here is to look at the otherDownloads2 string
+     in downloads.properties, and make a reasonable estimate of its
+     maximum length. For English, this seems like a reasonable limit:
+
+     + 999 other downloads

+   *            pressed, is passed an object that contains the following fields:
+   *              - checkboxChecked: (boolean) If the optional checkbox is checked.

+   *        as mainAction. These are used to populate the notification button's
+   *        dropdown menu.
+   * @param options
+   *        An options JavaScript object holding additional properties for the
+   *        notification. The following properties are currently supported:
+   *        persistence: An integer. The notification will not automatically
+   *                     dismiss for this many page loads.
+   *        timeout:     A time in milliseconds. The notification will not
+   *                     automatically dismiss before this time.
+   *        persistWhileVisible:
+   *                     A boolean. If true, a visible notification will always
+   *                     persist across location changes.
+   *        dismissed:   Whether the notification should be added as a dismissed
+   *                     notification. Dismissed notifications can be activated
+   *                     by clicking on their anchorElement.
+   *        eventCallback:
+   *                     Callback to be invoked when the notification changes
+   *                     state. The callback's first argument is a string
+   *                     identifying the state change:
+   *                     "dismissed": notification has been dismissed by the
+   *                                  user (e.g. by clicking away or switching
+   *                                  tabs)
+   *                     "removed": notification has been removed (due to
+   *                                location change or user action)
+   *                     "showing": notification is about to be shown
+   *                                (this can be fired multiple times as
+   *                                 notifications are dismissed and re-shown)
+   *                     "shown": notification has been shown (this can be fired
+   *                              multiple times as notifications are dismissed
+   *                              and re-shown)
+   *                     "swapping": the docshell of the browser that created
+   *                                 the notification is about to be swapped to
+   *                                 another browser. A second parameter contains
+   *                                 the browser that is receiving the docshell,
+   *                                 so that the event callback can transfer stuff
+   *                                 specific to this notification.
+   *                                 If the callback returns true, the notification
+   *                                 will be moved to the new browser.
+   *                                 If the callback isn't implemented, returns false,
+   *                                 or doesn't return any value, the notification
+   *                                 will be removed.
+   *        neverShow:   Indicate that no popup should be shown for this
+   *                     notification. Useful for just showing the anchor icon.
+   *        removeOnDismissal:
+   *                     Notifications with this parameter set to true will be
+   *                     removed when they would have otherwise been dismissed
+   *                     (i.e. any time the popup is closed due to user
+   *                     interaction).
+   *        checkbox:    An object that allows you to add a checkbox and
+   *                     control its behavior with these fields:
+   *                       label:

+   *                       checked:
+   *                         (optional) Whether the checkbox should be checked
+   *                         by default. Defaults to false.
+   *                       checkedState:
+   *                         (optional) An object that allows you to customize
+   *                         the notification state when the checkbox is checked.
+   *                           disableMainAction:
+   *                             (optional) Whether the mainAction is disabled.
+   *                             Defaults to false.
+   *                           warningLabel:
+   *                             (optional) A (warning) text that is shown below the
+   *                             checkbox. Pass null to hide.
+   *                       uncheckedState:
+   *                         (optional) An object that allows you to customize
+   *                         the notification state when the checkbox is not checked.
+   *                         Has the same attributes as checkedState.
+   *        popupIconURL:
+   *                     A string. URL of the image to be displayed in the popup.
+   *                     Normally specified in CSS using list-style-image and the
+   *                     .popup-notification-icon[popupid=...] selector.
+   *        learnMoreURL:
+   *                     A string URL. Setting this property will make the
+   *                     prompt display a "Learn More" link that, when clicked,
+   *                     opens the URL in a new tab.

+/*
+ * This module implements the front end behavior for AeroPeek. The taskbar
+ * allows an application to expose its tabbed interface by showing thumbnail
+ * previews rather than the default window preview.
+ * Additionally, when a user hovers over a thumbnail (tab or window),
+ * they are shown a live preview of the window (or tab + its containing window).
+ *
+ * In Windows 7, a title, icon, close button and optional toolbar are shown for
+ * each preview. This feature does not make use of the toolbar. For window
+ * previews, the title is the window title and the icon the window icon. For
+ * tab previews, the title is the page title and the page's favicon. In both
+ * cases, the close button "does the right thing."
+ *
+ * The primary objects behind this feature are nsITaskbarTabPreview and
+ * nsITaskbarPreviewController. Each preview has a controller. The controller
+ * responds to the user's interactions on the taskbar and provides the required
+ * data to the preview for determining the size of the tab and thumbnail. The
+ * PreviewController class implements this interface. The preview will request
+ * the controller to provide a thumbnail or preview when the user interacts with
+ * the taskbar. To reduce the overhead of drawing the tab area, the controller
+ * implementation caches the tab's contents in a <canvas> element. If no
+ * previews or thumbnails have been requested for some time, the controller will
+ * discard its cached tab contents.
+ *
+ * Screen real estate is limited so when there are too many thumbnails to fit
+ * on the screen, the taskbar stops displaying thumbnails and instead displays
+ * just the title, icon and close button in a similar fashion to previous
+ * versions of the taskbar. If there are still too many previews to fit on the
+ * screen, the taskbar resorts to a scroll up and scroll down button pair to let
+ * the user scroll through the list of tabs. Since this is undoubtedly
+ * inconvenient for users with many tabs, the AeroPeek objects turns off all of
+ * the tab previews. This tells the taskbar to revert to one preview per window.
+ * If the number of tabs falls below this magic threshold, the preview-per-tab
+ * behavior returns. There is no reliable way to determine when the scroll
+ * buttons appear on the taskbar, so a magic pref-controlled number determines
+ * when this threshold has been crossed.
