Firefox Dev can’t establish a connection to local server

I'm a web developer that setup a local environment under Linux Mint.

For some reason, Firefox Developer Edition (59.0b7 64-bit) cannot access sites on my localhost. The interesting thing is that Firefox Quantum 58.0.1 (64-bit) is showing these local sites perfectly fine. I've tested other browsers, including Konqueror and Lynx, and these work fine also.

I've setup my environment so that apache2 can serve pages from a 'wildcard' virtual host. Using symlinks, I can link my project files to another directory that functions as the web root. Thus:

/home/me/business/projects/client/index.html => /home/me/business/www/client/index.html

Navigating to http://client.dev brings up the page perfectly in Firefox 58, Konqueror, and Lynx.

However, Firefox Developer Edition, AND Google Chrome, both fail to load the page. The URL changes from http://client.dev to https://client.dev and throws this message:

"Unable to connect

Firefox can’t establish a connection to the server at client.dev."

I've played around with the about:config settings for Network.dns.* but nothing seems to help. Also, the apache logs do not produce anything useful.

Your input will be greatly appreciated.

How do I bypass "Error code: SSL_ERROR_WEAK_SERVER_EPHEMERAL_DH_KEY" on trusted site?

I have a local Linux server in my office we use for our point of sale system. I almost never need to log in to it, as we have an outside support company that handles most of it. In this instance they want me to login and look at something, so they sent me an email telling me to login using a particular https internal address (https://192.168.1.1:1311 for example). I know nothing at all about Linux except how to spell it, so they have me use Dell Open Manage so it has a more "windows type" interface. However, I can't log in because of the security error I listed above. Screenshot attached. I cannot find a way to force FF to ignore it or bypass it or whatever. Any suggestions?

I am running Firefox 55.0.3 on an iMac El Capitan. I keep getting Access Denied; you don't have permission to access (URL) on this server, for a few sites only (sites I've accessed in the past). I've cleared cookies, cache, and history, I've refreshed Firefox, I've disabled all add-ons/plug-ins/extensions. I've also tried the sites with other browsers (so, yes, I know it's not just Firefox, but I was hoping maybe you could help anyway...) Thank you.
