KeePassHttp-Connector oleh Andy Brandt

KeePassHttp-Connector is a WebExtension for browsers to send and receive credentials from KeePass(XC).

This is a port of the ChromeIPass extension for Chrome, but compatible with Firefox 55+.

Note:
Because Firefox does not offer an API to communicate with the built-in password manager KeePassHTTP-Connector needs to implement its own kind of password manager.
