Display history menu, tab list menu, bookmarks menu, toggle tab groups, panorama or various sidebars with middle mouse button.
This add-on is for you if you miss the behaviour of your computer's window manager/taskbar in your browser. It remembers the order tabs are opened and focused so when closing or minimizing a tab the previously active one gets the focus.
