Long delays with HAProxy
I have a Plesk (apache) server that is behind HAProxy. When I connect securely to a web site through HAProxy using Firefox, I get long delays. If I use Safari or Chrome, the pages come right up without any delay.
If I connect to the Plesk server directly without HAProxy in the middle, there are no delays.
I do not know what would cause these delays that don't occur with other browsers.
I'm on a Mac: 115.0.2 (64-bit)

Figured it out. It was DNS over HTTPS which is why all other browsers worked. They all use my resolver for DNS. That setting should probably not be enabled by default. The browser shouldn't do its own thing when it comes to DNS resolution without asking first.

Gotcha... I will see if I can set up access for the outside world and check. Any by securely I mean HTTPS. Everything now is internal. Thank you.

You can configure a canary domain on your network to tell software you want to use your own resolver.
"You can configure a canary domain on your network to tell software you want to use your own resolver."
Not "software", just Firefox, and as the link you pointed me to states, canary domains is a hack to get around another hack.
Browsers should browse. If a browser also wants to be a DNS forwarder it should not do that by default or give a warning the first time such a "feature" is added to an update and confirm the user wants their browser doing something other than what is expected and what other software was specifically designed to do. This is the kind of nonsense Microsoft does which makes their products bloated, unpredictable, and unreliable.
