Multiple Tab Handler by Piro (piro_or)

This provides features to handle multiple tabs at once, for example, close them, reload them, and so on. When you press the mouse button and dragging over tab items in the panel, they will be selected. After you release the button, the popup to choose command will be shown. Of course, you can toggle selection by Ctrl-click on each tab and call features from the context menu. Yes, the behavior looks like Excel.　And you can also close multiple tabs directly by dragging on closeboxes.

Moreover, this addon is designed to work with Tree Style Tab. If you install both addons, you can select tabs in the sidebar by dragging . (Note that you need to long-press on a tab to start selection. Otherwise - if you start dragging immediately, it just moves the tab.)
