• Works on Firefox 25 and later.
• Fixed: Restore tree structure correctly for "undo close tab" feature, even if the tab had no child. (It was a regression on the version 0.14.2013052901.)
• Improved: New tab from DragIt is opened as a child of the current tab.
• Fixed: Don't shrink tab bar automatically, when the user selects a background tab.
• Improved: Update label of Firefox's "Close Tabs to the Right" menu item to "Close Tabs to the Bottom" in the vertical tab bar.
• Fixed: Don't break tree structure by drag and drop of a child tab to move it to the upper level.

• Fixed: On Firefox 23 and later, ignore the preference "hide the tab bar when there is only one tab" because it was available on Firefox 22 or older versions.
• Fixed: Resolve visual glitch of the tab bar after showing/hiding a toolbar.
• Fixed: Works with bug489729 (Disable detach and tear off tab).
• Improved: Introduce the concept "temporary group tab" and "permanent group tab". And close needless group tabs automatically only when it is marked as temporary. Automatically opened group (dummy) tabs are temporary, and manually opened tabs are permanently by default. You can make group tabs always permanent by these preferences extensions.treestyletab.openGroupBookmark.temporaryGroup (for bookmark groups) and extensions.treestyletab.createSubtree.underParent.temporaryGroup (for "create new tree from selected tabs" feature) with the value false.
• Fixed: Show/hide tab bar correctly after the grippy is clicked.
• Fixed: Don't freeze on the interface to edit bookmarks, even if there are too many bookmarks in the same folder.
• ru locale is updated by Infocatcher. Thanks!
