  Facebook applications are one of the reasons for Facebook attractiveness.
Unfortunately, numerous users are not aware of the fact that many malicious
Facebook applications exist. To educate users, to raise users' awareness and to
improve Facebook users' security and privacy, we developed a Firefox add-on
that alerts users to the number of installed applications on their Facebook
profiles. In this study, we present the temporal analysis of the Facebook
applications' installation and removal dataset collected by our add-on. This
dataset consists of information from 2,945 users, collected during a period of
over a year. We used linear regression to analyze our dataset and discovered
the linear connection between the average percentage change of newly installed
Facebook applications and the number of days passed since the user initially
installed our add-on. Additionally, we found out that users who used our
Firefox add-on become more aware of their security and privacy installing on
average fewer new applications. Finally, we discovered that on average 86.4% of
Facebook users install an additional application every 4.2 days.
