content: I found this thread to see if Vivaldi still does that. https://forum.vivaldi.net/topic/5049/why-does-vivaldi-connect-to-these-ips-on-startup/20 TL;DR: The Google IP addresses it contacts are for Google's Phishing and Malware protection feature, aka Safe Browsing. The 2nd page mentions how that is obviously used by Google to produce a list of URLs you visit, in what order, and they almost certainly sell that information. I mean... if I'm going to bother worrying about my browser contacting Google, I'll just block those IP addresses.
