goto addon Preferences to enable showing its widget in URL bar then click widget to copy URL ... perfect ... simple it just works

Just what I was looking for! Simple and functional. This feature should be native to Firefox. Only thing is that the "dark mode" option doesn't seem to work (at least, not in Zen browser).

This addon is extremely powerful! ❤️‍🔥

A very well working addon. Can you add a option warning popup when the link is copied?

Excellent solution - especially after the default button went missing in Firefox 90. It is the best tool for this purpose.
