Install the lastpass binary in addition to the browser plugin. It re-adds that functionality back.

I'm using lastpass with firefox nightly and I don't have this issue. copying the password to clipboard without seeing it works out of the box using the browser extension.
In bitwarden it works out of the box, so I think it’s just laziness.
Is anyone aware of a technical reason that copy to clipboard is absent in Firefox, or is just laziness? If laziness, I'll dump them tomorrow.
