I tried a number of extensions without replicating the issue. Then I downloaded the mega.nz extension and the nautilus integration and ran them. Then my computer got wonky right away and freezing every 5 seconds. So I recorded the output from cli and attach it. The firewall alert seems to be my phone being interested in my laptop.
