DNS_PROBE_STARTED only with Chrome not Firefox?

Hello,

it's a typical message from Chrome (and its cousins Edge or Brave) when it loses connectivity with the configured DNS resolver.

Are you using the one provided by the router?

As long as it’s not permanent, it's not a big deal.

Firefox is more polite and will usually say something like this:

 Hmm, we're having trouble finding that site.

And there you go ....

But goodness, those line spaces are really annoying!!

I have NextDNS which filters, as a Custom DNS. Additionally, the Portmaster firewall filters, but with my personal DNS, so I don't see where it's blocking; let's say it works again, it crashes alternately under Chrome...

As I use both browsers.. when I say filter I may be expressing myself poorly, sorry...

Portmaster was blocking access... It's all good "allow domain".
