Hi!

I'm developing a cite on my machine. It uses fake ssl certificate. It was added to exception and worked fine until last time. Now its impossible to add an exception. I see only this: http://content.screencast.com/users/SStub/folders/Snagit/media/77a3d2ae-0e1f-4807-aa2f-afc36a4173d8/07.22.2016-11.18.png In Chrome certificate exclusion works just fine. I checked solutions about antivirus and firewall. How can I turn this feature off?

Thanks!

hello, your site shouldn't send a hsts heather when you want to be able to add an exception for it: https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security you can clear the existing list of stored hsts-domains by going to your profile folder and deleting the SiteSecurityServiceState.txt file while firefox is closed.
