Supplies a needed function that should be standard. Wish there was one for Chromium-based browsers. Thanks.

Does not work for me under Linux openSUSE 15, but seems to work under Windows 7...

Works great. thank you

FANTASTIC! single copy-tab capability without the "Access all data" permission that can allow deceptive extensions access to your passwords.

Works perfect. No modification to Firefox needed.

There are other add-ons similar to this that allow copying all open tab URLs, but this one allows you to copy just a single tab URL.

Exactly what I needed. Thanks.

Works just as advertised, out of the box. No fuss.

Thanks :)
