In November 2014, Mozilla announced the launch of its open-source application Stumbler on the Android operating system only, and the task of the application to collect information about the sites of Wi-Fi networks and towers on the phones of users, the application has witnessed a significant decline in user activity and also declined By its developers, and now it seems that the application is in its final stages where it is no longer available in Google Play Store.
Mozilla has not officially announced this removal, but if it is killed forever, it is not surprising. In the context of the topic, a Mozilla engineer replied to a user inquiring about Stumbler's condition. "The data collected from Firefox outweighs the contributions of the custom Stumbler application, , And is scheduled to be closed in particular in the near future. "
Therefore, it is very likely that this step is the first to get rid of the Stumbler application and turn it off completely, and rely on Firefox, finally the Stumbler application page continues on the Mozilla site, and the APK application file is also available for download and action, but on the Google Play Store you will see the phrase " Sorry, the requested URL was not found on this server ".
