download.tensorflow.org doesn’t support a secure connection

1. The entire URL of the documentation with the issue

https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/tf1_detection_zoo.md

2. Describe the issue

When I click the links under COCO-trained models it should download the file, but it opens a website for a second, closes by itself and nothing happens.
So when I tried doing the same in incognito mode, this time it opens a website, but doesn't let me connect to it saying download.tensorflow.org doesn’t support a secure connection. You are seeing this warning because this site does not support HTTPS and you are in Incognito mode.

Hello @samuelwhiskeyjohnson

This is a client-side issue rather than a problem with the respository,

download.tensorflow.org doesn’t support a secure connection

is due to the reason that the downloads links are not HTTPS connections instead they are HTTP only.
example: http://download.tensorflow.org/models/object_detection/ssd_mobilenet_v1_coco_2018_01_28.tar.gz
you can see that there is no https protocol. The browser probably refused any not HTTPS connection in the Incognito mode.

When I click the links under COCO-trained models it should download the file, but it opens a website for a second, closes by itself and nothing happens

This is a specific error that I can't recreate.
But, you can use wget or curl. This way you can directly download the files from command line:

wget http://download.tensorflow.org/models/object_detection/ssd_mobilenet_v1_coco_2018_01_28.tar.gz

Edited:

I tried one of the download links with Mozilla Firefox and yea it does blocks the download

But after manually allowing it the download starts without any further issues :

I'll suggest check you browser settings.
