one-click-duplicator автор chv

This is very simple addon - lets you duplicate the active Tab to new tab, in one click.

Because of in firefox there is no shortcut to duplicating tabs, Users familiar with this option can be very disappointed. With this plugin you can duplicate the current tab:

* By clicking on the plugin icon (which can also be placed next to the 'back' and 'next' buttons, it's really convenient. instructions below)
* By clicking on the shortcut: Ctrl+Alt+D

You can place the addon button everywhere on the upper tollbar. right-click on the addons bar, beside the address bar, and choose "Customize" - then you can drag the icon to the place you want.
