Empfehlungen sind eine an Nutzer angepasste Liste von Apps. Diese Empfehlungen werden mithilfe anonymer Installationsdaten registrierter Marketplace-Nutzer algorithmisch berechnet.

Beachten Sie bitte: Empfehlungen sind derzeit noch nicht verfügbar, werden aber in den nächsten Wochen bereitgestellt.

Wer sieht App-Empfehlungen?

App-Empfehlungen im Firefox Marketplace werden Nutzern angeboten, die:

• ein Firefox-Konto besitzen und während der Verwendung des Marketplaces mit diesem angemeldet sind.
• das Erhalten der Empfehlungen nicht abgeschaltet haben.

Wie (de-)aktiviere ich diese Funktion?

You can choose to opt in or out at any time. Opting out will also prevent your data from being used (anonymously) to calculate recommendations.

1. When you've logged in, click on the settings icon, then choose Edit Account Settings.

   

2. Put a check mark next to Yes, show me recommendations based on my installed apps. Uncheck the box to opt out.

Wie funktioniert das Empfehlungs-System?

The recommendation system used in the Firefox Marketplace is developed by Telefonica Research Labs. The system provides better and more personalized recommendations as you install more apps. Before you install any apps the system recommends apps based on their popularity since the algorithms do not have enough data to discover personalized tastes.

The main technique used in the recommendation system is called kollaboratives Filtern (CF). It is a recommendation technique which generates personalized recommendations for a user using opinions of other users who have similar taste.

The specific CF technique used is called Matrix Factorization, which originated here. The exact algorithm used is described in this research paper. We use only anonymized user app installations data and don’t use other information described in this paper such as home vs work location.

Wie werden Daten gesammelt und verwendet?

When you log in to the Marketplace and install an app, Marketplace records the application, the country of installation, date and time of installation, and language preference. It does not know if you actually like the app, used the app, or removed the app.

User data used in calculating recommendations include:

• apps installed and date of installation
• country setting of user
• language setting of user

If you install apps while you are not logged in, Marketplace has no record of your app installation and does not record any information other than the fact that the app was installed by someone in a particular country.

All the data is stored and processed within the Mozilla Virtual Private Network. We never share any of this information with the app developer and adhere to the terms of the Marketplace Privacy Policy where we use data to improve the user experience.
