Firfox is enforcing https on web pages hosted on Ubuntu server running on Virtual Box in local machine; how to disable it?
My host machine is Mac (OS X EI Capitan Version 10.11.6). On top of it I am running Virtual Box (5.2.6). Within Virtual Box I have Ubuntu Machine with Apache2 running. I am running a development domain sandbox.dev:8080. I use this setup for testing purposes. I have my test projects stored in a shared folder between the host and guest machines. All the setup was up and running with FireFox and Safari whether I wanted to use http or https for test purposes (And the setup is still running in Safari) until I got an extension Cookie Editor for FireFox and along withit my FireFox got updates. After that firefox started behaving strangely! 1- It is trying to enforce https on all the pages on the Ubuntu VM 2- It is allowing http on real website (This I tested by removing SSL Certificate from one of my websites)
I have tried some solutions like clearing history, about:config (Though could not locate New Integer) but of no avail. It would be great if someone may help me and I may open my sites in the VM both in http and https as I desire. Thanks in advance

Note that you can no longer use the .dev domain because its owner (Google) has added this domain to the HSTS preload list and thus a secure connection is automatically enforced.
The ".dev" domain landed on the HSTS preload list in Firefox 59.0b7 and this means that Firefox will automatically try a secure connection to these TLDs.
Thank you very much for a great reply. Now I am thinking of using some other domain like sandbox.zeb. Any suggestion so that I may not run into the same issue once again?
I don't know what kind of domain name would be best to use. Maybe a combination would work.
You can also try to ask advice at the Stack Overflow forum site to see whether they have some suggestions.
