Duplicate Firefox Tabs [Round Up]

Previously, I mentioned about a neat Firefox trick that allows you to duplicate the tab on the fly by just dragging it to a new space. Anyway here what I failed to figure out, and thought would be cool to have:

1. Support Mac’s Firefox
2. Keyboard shortcut instead of mouse dragging

Thanks for readers tip-in, there’s work around for both now.

Firefox in Windows

[Mouse] - Hold Control, drag tab to new space.

[Keyboard shortcut] - Click URL (highlight), Alt + Enter

Firefox in Mac

[Mouse] - Hold Command, drag tab to new space.

[Keyboard shortcut] - Click URL (highlight), Option + Enter
