  • Fixed: "extensions.treestyletab.autoExpand.intelligently" works correctly. If you set the preference to false, not-focused trees are never collapsed by expansion of the newly focused tree.
  • Fixed: Don't forget collapsed state of trees while toolbar customizing.
  • Fixed: Create tree of nested bookmark folders, from dragged tree correctly.
  • Fixed: Open tabs as a tree on the dropped position in the tab bar, from dragged bookmark tree.
  • Fixed: Update tab bar appearance when contents of the browser bottom box is shown or hidden.
  • Fixed: Move the dragged pinned tab to the dropped position correctly, even if the drop target is the first pinned tab.
  • Fixed: Expand collapsed children of newly pinned tab automatically. (Child tabs unexpectedly vanished when a parent tab with collapsed children was pinned.)
  • Fixed: Don't break tree structure when a last child tab is moved to the upper level by drag and drop.
  • Fixed: After session restorations, new tabs related to the current tab could be shown as broken tree because TST's internal caches were lost. Now, session restorations work more stablely.
  • Fixed: "Fast restoration of tree structures on the startup" feature couldn't work correctly on some environments.
  • Fixed: Suppress freezing from infinity loop which is caused by recursive reference (it can be there unexpectedly by some reasons!) of tabs.
  • Fixed: Show bottom border of the toolbox for the vertical tab bar and "Tabs on Bottom" toolbox.
  • Fixed: Show notification about newly opened tabs at out of the viewport correctly, on Linux.
  • Fixed: Update "Metal" skin for Firefox 14 and later.

  • Fixed: Respect special behaviors defined in Firefox itself or other addons for middle-click on the new tab button.
  • Fixed: Fix NS_ERROR_XPC_BAD_OP_ON_WN_PROTO error in auto-shrink mode.

  • Fixed: Store and restore the original state of the "Tabs on Top" feature when TST is uninstalled.
  • Fixed: Don't reset "Tabs on Top" state on the startup. (It was wrongly enabled on every startup.)
