I was just coming in to say exactly this. I cannot tell you the number of times IT has told me “there’s nothing wrong with the network” or “no one else is complaining”, yet when I whip out the old trusty packet capture showing missed packets, firewalls sending a TCP RST, etc., then their tune changes. It’s like Confucius always said, “the packets don’t lie”.

I learned about containers less than year ago and kicked myself for not learning about them sooner. Containers in Firefox truly are a godsend.
