Why is Firefox making these outbound connections?
(infosec.pub)
I have all Firefox Data Collection and Use options disabled.
Anyone know what all of these services are doing? I assume they're for auto updates, account sync, and maybe pushing Pocket ads and/or sponsored pins?
Likely, I'll block most, but curious if anyone knew.
Detectportal is for captive portal detection, so that firefox knows if you need to log in on a captive portal before using the public wifi network you are connected to.
If that's a stationary computer, that's probably not needed, it can be disabled in about:config so it's easier on the firewall
