Rated 3 out of 5 stars

For Duplicate this tab:
One thing that's missing from this port over is an icon for the add-ons screen (even a default icon of a jigsaw piece)

By removing the following line from the install.rdf the default icon shows up under 3.6
Note Firefox 4.0b10 still has no icon shown. The file referenced above does exist at the above location though.

This review is for a previous version of the add-on (1.1).  This user has other reviews of this add-on.
