Firefox 59 x64 errors driving me insane...

[AMD64Blondie]

So I just recently updated Firefox to the newest version (59 right now..this is on Windows 10 Pro 64-bit.)

Now whenever I try to launch Firefox, it doesn't connect,and gives me this error:
Your connection is not secure

The owner of www.amazon.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.

(direct copy and paste of the error message.)

(The site listed varies depending on which site I'm trying to connect to-used amazon.com as a example.)

Bizzarely,other browsers actually work perfectly.I've tested Opera 12.18 x64,Vivaldi,Google Chrome 64 x64,and Microsoft Edge.They all connect to the internet perfectly,and work normally.

It's too weird that it's only Firefox giving me so much trouble.

This keeps getting weirder.I downloaded Firefox 52 ESR to see if it worked.NOPE.same error as with the new Firefox 59.

Does this work? (shamelessly ripped from somebody named cor-el):

"You can edit the SiteSecurityServiceState.txt file in the Firefox profile folder and remove lines that refer to a specific domain. Then you may be able to add an exception on the next visit."
