KeePassHttp-Connector is a powerful WebExtension designed to seamlessly integrate KeePass and KeePassXC password managers with modern browsers like Firefox 55+ and Chrome. It securely communicates with KeePass using the KeePassHttp plugin over HTTP, allowing users to retrieve and update credentials directly within the browser environment.

Key features include support for multiple KeePass databases with unique icons, a built-in password generator, handling of multiple credential sets per page with easy selection UI, and autofill capabilities for username, password, and even dropdown fields. It also supports HTTP authentication (htaccess-login), integrates with context menus and shortcuts for ease of use, and automatically detects username-password field combinations to streamline logins. Regular checks ensure the KeePassHttp plugin stays up to date. Installation instructions are provided for quick setup and smooth operation.

User reviews

KeePassHttp-Connector is valued for enabling KeePass integration with Firefox through a minimalist design and effective autofill, especially when paired with OTP plugins. However, multiple users report that the add-on breaks with Firefox 69 and newer versions, leading to connection failures and installation errors. Concerns are raised about the security risks of its status as an individual developer project without Mozilla's official security validation, risking overlooked vulnerabilities. Despite these issues, dedicated users appreciate ongoing efforts to maintain functionality and fix bugs over time.

Pros

Provides a useful solution for integrating KeePass with Firefox, facilitating password management.
Minimalist design that functions similarly to Firefox's built-in password manager.
Supports autofill functionality effectively when properly set up.
Active development and bug fixes addressing browser updates, appreciated by longtime users.
Works well in conjunction with OTP plugins, enhancing security and usability.

Cons

Compatibility issues with Firefox versions 69 and later, causing the add-on to stop working properly.
Users encounter errors when trying to connect, such as the 'Connect' button doing nothing.
Concerns about security risks due to the add-on being developed and maintained by an individual without official Mozilla security vetting.
Some users report installation problems, including messages indicating the module may be corrupted.
Potential security vulnerabilities due to lack of official oversight and possibility of overlooked issues.

Ich finde es interessant, dass sich jemand diese Mühe macht, eine derartige Lösung zu entwickeln. Was mir prinzipiell nicht gefällt bei einem derart sensiblen Thema, ist, dass eine Einzelperson so etwas bereitstellen kann, ohne dass Mozilla hier irgendeine Security-Qualitätssicherung gewährleistet. In meinen Augen absoluter Wahnsinn. Dem Autor möchte ich hier nichts unterstellen, aber gerade Einzelkämpfer können leicht manche Sicherheitslücken übersehen. Die Lösung ist super und ich wäre glücklich, wenn Keepass das offiziell übernehmen würde!

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

KeePassHttp-Connector requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

KeePassHttp-Connector has earned a fairly good reputation and likely can be trusted.
