I assume you use Chrome in this section
Click the “Not Secure” box near the address bar, and a little panel should show up:
Certificate item in the box, and you should see another panel show up, with the certificate details:
Now drag the certificate icon from there to the desktop, or any other folder you want. Literally drag and drop using the mouse.

Now double-click that, and this window should show up:

cmd-Q) and try reloading your Chrome tab, it should work!
And it should now work across any browser you use.
