I have the store user with this feature activated. Ive tried in explorer and Firefox.

When I click the button in Explorer, a popup will ask me to give access to the page for the clipboard, but no url in clipboard.
When I click the button in Firefox button changes color, but nothing happens.

I believe the URL will be copied.
Have you tried to use paste in a blank document (like word) after clicking the button?

David

Yes it pasted what was previously in the clipboard.

Hi Steven, I just tested that on my site and the entire button there changes to show the url when clicked.
If that's not happening, I suggest checking the ectcart.js file to be sure the last time you updated, that that file got updated too.
You can also hit F12 and view the "console" in your browser to see if any javascript errors exist.

David

Thanks. I'll try updating.
