Pingsender: If you monitor the connections your computer makes, you may notice that a program called pingsender.exe connects very often to Internet.
Depending on the program or service you use to track connections, you may have additional information. For example, the Windows Firewall Control displays the IP address of the connection and company who digitally signed the executables archives.
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 archive.
Firefox collects data if telemetry is enabled. Your browsing transfers data very often to Mozilla.
This means that Mozilla has data from the program browsing.
Pingsender is activated and starts as a separate process during duration terminates Firefox and attempts to send telemetry data collected during your browsing session.
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.
If you now want to see what data Mozilla collects through Firefox, go to about: telemetry in Firefox.
