Please update "Duplicate Tab" to work with Firefox 3.5+.
This is the first Add-On I install every time.

Good Question: Why isn't this part of the default Firefox?
It is in Opera.

Firefox 3.5 has an option to open an existing tab in a new window. Why not in a new tab in the same window? It should be very easy to do.

I use this Add-On the most.
I'm thinking of uninstalling Firefox 3.5 and going back to Firefox 3.0.11 to have this option again.
