Copy Tab URLs by Firefox user 13243341

This lightweight add-on provides a button to copy to the clipboard the URLs of all tabs of the current window.

This add-on does NOT remove duplicates from the list of URLs, and it DOES include URIs like about:home and about:blank in the list.

Designed (icon colour) to go nicely together with the Paste and Go Button extension.

Pro tip: Install as a third the Copy Selected Links extension; these three combined form a nice replacement for the Copy Urls Expert extension, which is now "Legacy".
