When I run iftop -P to see what is coming to/from my interface, I constantly see connections to Amazon, HTTPS protocol:=> ec2-176-34-135-167.eu-west-1.compute.amazonaws.com:https<==> ec2-52-22-162-249.compute-1.amazonaws.com:https<=...Those connections reappear when I close and open my browser (Iceweasel, Debian testing). I cleared the cache and cookies but this is somehow persistent. I also disabled Amazon as a search engine. I do not own a cloud storage, neither a virtual machine on AWS.How to trace the source of those connections?Best Regards,KamilEDITOutput of lsof -i -nP, as requested by @thrigiceweasel 8596 user   38u  IPv4  90162      0t0  TCP 192.168.0.15:49156->216.58.209.78:443 (ESTABLISHED)iceweasel 8596 user   47u  IPv4  90186      0t0  TCP 192.168.0.15:51544->52.25.142.225:443 (ESTABLISHED)iceweasel 8596 user   53u  IPv4  86275      0t0  TCP 192.168.0.15:42090->52.32.59.229:443 (ESTABLISHED)iceweasel 8596 user   55u  IPv4  90184      0t0  TCP 192.168.0.15:50570->52.11.148.42:443 (ESTABLISHED)iceweasel 8596 user   56u  IPv4  87223      0t0  TCP 192.168.0.15:44370->54.187.136.191:443 (ESTABLISHED)Hmm, there is Google too, maybe those are search engines updates?NO. I disabled search engines autoupdates and restarted the browser. I also disabled Firefox (Iceweasel) Sync service, didn't help (I thought that maybe they store my data in Amazon cloud).
