after dns resolution some page does not load for 60s (e.g. google.com)
I'm running some devices with windows 10 and 11. All have same most current version of Firefox installed. There is no issue on Win10. With any Win 11 device, some pages as google.com take about 60s until they start loading. Once started the behavior disappears until restart of the browser (even tab gets closed). I'm using classic DNS (no DoH).
Here I've uploaded the profile: https://share.firefox.dev/4coxRg4
On Network it say's "DNS request 6ms", "after DNS request 60000ms".
With wireshark I can see different kind of DNS request on Win10 A and AAA gets request, on Win11 HTTPS gets request - no idea if that makes the difference as there in no delay in the response anyway.
Any idea how to troubleshoot this?
