Firefox – Copy tabs

One of the reasons why I absolutely love Mozilla Firefox is the fact that the system of tabs is so excellently implemented. At times I want to be able to copy a tab. There are two simple ways of doing this:
 
Method one: mouse
By simply holding down the Ctrl-button on our keyboard while dragging a tab (as if to relocate it) you instead create a copy of the tab where you drop the tab.
 
Method two: keyboard
Start by clicking Ctrl+L to activate the address bar. Then press Alt+Enter. This will copy the current tab to a new tab located at the far left of the list of tabs.
