Invalid PIN unlocks my vault in Firefox

I have enabled unlocking by PIN in Firefox and then press “Lock”. Bitwarden hides the vault and displays a PIN prompt. I enter a wrong PIN and get access to my vault. Why so?

Before seeing this I didn’t even know there’s a PIN unlock option. I just tried it and sure enough it only throws an error as wrong pin entered but the vault still unlocked!

A hotfix was just issued, version 1.39.1. Add Ons -> Extensions -> Settings Button near top right -> Check for updates. That should pull the latest Bitwarden version.

It’s working now with the latest version, thanks.
