Lawki от Erem

Lawki is a browser extension for the Lawki password manager. It automatically detects login forms on any website and adds a fill button next to password fields. Click the button to see your saved credentials for the current site, select an account, and autofill both username and password instantly.
You can also open the popup to view and copy credentials for the active tab.
All communication happens locally between the extension and the Lawki desktop app through Firefox's native messaging API. No data is sent to any server. Credentials never leave your machine.
Requires the Lawki desktop application to be installed and running.
