Firefox is uploading lots of data during startup to servers like
ec2-52-89-171-193.us-west-2.compute.amazonaws.com.https. Is there a way to find what data are being uploaded to any particular server and how is firefox uploading my data? Because my default home page in firefox is only google.com but there are lots of websites showing up during tcpdump and through wireshark.
Is there any recommended resources which I can go through to find out more about this?
