Quick Tip: Duplicate Current Tab in New Window in Firefox

As both a programmer and writer, I often find the need to open my current tab into a separate window so that I can move it to my second monitor. Tab Mix Plus to the rescue! There’s an option in the settings panel to easily duplicate the current tab in a new window. You can use it from a keyboard shortcut as well if you want.

Notice the new option for “Duplicate in New Window” when I right-click a tab. You can also use the shortcut key of Ctrl+Shift+N whether you enable this menu option or not.


To add the item to the right-click menu, go to the Tab Mix Plus Options screen, click on the Menu button at the top, and then Tab Context Menu.


In here, you can click the “Duplicate in New Window” checkbox to enable the menu item.
