Error installing firefox nightly

[ultra99]

I’m trying to install firefox nightly from package manager AUR, but I’m receiving this error:

20211104-firefox-96.0a1.en-US.linux-x86_64.tar.bz2 ... FAILED (bad signature from public key EBE41E90F6F12F6D)
==> ERROR: One or more PGP signatures could not be verified!
Failed to build firefox-nightly

Any ideas?

Detail Many AUR packages contain lines to enable validating downloaded packages though the use of a PGP key.
