Copy All Tabs por Charles

Copy All Tabs is a Firefox Add-on that takes the address and title for each tab and creates a text list of links. The list is copied to your clipboard so you can paste it to notes. You can also open tabs from a previously saved list of links.

The extension is open source software. Source code is available here:

This Add-on is functionally similar to CopyAllUrls (http://www.plasser.net/copyallurls/). I have used that add-on for many years with Firefox (Thank you, Jürgen!). The author has indicated that it is no longer being maintained. Now that Firefox requires Add-ons to be signed, the original is being blocked by Firefox.

It is also similar in functionality to Copy All Urls on Chrome, but I have not found something similar on Firefox:
