If you use Chrome, Google can use a network protocol for tracking and ad delivery that can't be seen or blocked by extensions. TL;DR: You really shouldn't use a web browser made by an ad company.
"AdBlock Plus, uBlock Origin, and other extensions cannot block QUIC requests. Recommended best practice is to disable QUIC from the chrome://flags/ URL."

@desikn I've been on Edge for a bit, but am back on Firefox again due to "technical issues" with the new Windows version, and am so far impressed with where it's at.
It's really good to see that Firefox is zippy again. I moved off of it a while back because of how sluggish it had gotten.
