Icon Image fix for Add-ons screen (additional) Rated 3 out of 5 stars

In addition to what I typed below, to get an icon to show up in firefox 4 & 5

Once extension downloaded to desktop, open .xpi file
Go to folder “chrome\duplicatethistab.jar\skin\modern\duplicatethistab\”
Extract file labelled "tab-drag-duplicate-indicator.png"
Edit in a suitable programme that can resize by pixels
Resize image to 48x48 pixel, & save as Icon.png
Resize ORIGINAL file to 64x64, & save as Icon64.png
Merge back into .xpi file & drag into firefox to install

Add-ons icon 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
<em:iconURL>chrome://duplicatethistab/skin/icons/duplicatethistab-icon-small.jpg</em:iconURL>
Note Firefox 4.0b10 still has no icon shown. The file referenced above does exist at the above location though.

Add-ons icon Rated 3 out of 5 stars

From Duplicate tab there is a jigsaw piece that shows up in duplicate tab extension under Firefox 3.6. If you install duplicate tab extension into Firefox 4 beta 10 at time of typing this (needs a max version hack to get it to install), the jigsaw piece shows up.Contd.
