Pingsender: If you monitor the connections made by your computer, you might notice that a program called pingsender.exe is very often connected to the Internet.Depending on the program or the service that you use to monitor connections, you can have additional ones information. For example, the Windows Firewall Control displays the IP address of the connection and company who digitally signed the executables.
The image below shows a login attempt signed by Mozilla Corporation to an IP address owned by Amazon's AWS Cloud service.
You may also have noticed that pingsender.exe is activated every time you close the Firefox web browser.
The article “Getting Firefox data faster: the termination of pingsender” or “Getting Firefox data faster: the shutdown pingsender” of Alessio Placitelli provides additional information about the executable file.
Firefox collects data if telemetry is enabled. Your browser transfers data very often to Mozilla.
This means that Mozilla has data from the browser.
Pingsender activates and starts as a separate process during Firefox shutdown and attempts to send telemetry data collected during your browsing period.
Mozilla even managed to significantly reduce shipping time. According to Placitelli, 85% of pings reach Mozilla within an hour, and 95% do so within the first 8 hours.
In short: Pingsender is a separate process run by Firefox to send telemetry data to Mozilla.
