  • Fixed: Linux specific style rules were not loaded unexpectedly.
  • Fixed: On Linux + GNOME3, "narrow scroll bar" was not narrow.

  • Improved: While you are browsing tabs by Ctrl-Tab/Ctrl-Shift-Tab, now collapsed tree is automatically expanded, if you stay there with pressed Ctrl key.

  • Modified: The counter in a parent tab now reports the number of all tabs in the tree including itself.

  • Note: This version (and older versions) is incompatible to Firefox 8 or later due to the bug 455694 and 674925.
  • Improved: A dummy tab for grouping tabs is automatically closed when it has no sibling tab.
  • Improved: The size of pinned tabs can be customized by secret prefs "extensions.treestyletab.pinnedTab.width" and "extensions.treestyletab.pinnedTab.height". If you set the width to "-1", then pinned tabs will be expanded to the width of the vertical tab bar.
