Why does Add Exception button not work for self signed certs?
I recently updated my browser to Firefox 37.0.2 from FF 36. When I try to access a site that I have been developing the untrusted connection page shows up. Clicking the Add Exception button does nothing. The error is :(Error code: sec_error_unknown_issuer). I have tried manually adding the exception and I have tried deleting the cert8.db file that I found can be corrupted. I am using self signed certificates that work on the other major browsers but I still get nothing on Firefox. I am not the only person with this problem because I am part of a dev team and if we want to test on Firefox we have to downgrade to 36. Thanks for all help! P.S. I am also using Windows 7

This is a big problem in Firefox, unfortunately I cannot help you but I have found the same thing happen with random versions of Firefox and random self signed certificates.
Basically on Chrome or IE you can always say bypass, on Firefox you can occasionally save the exception fine and occasionally not. The same goes for other certificate issues too(like old certificates).
It also seems to change randomly between versions of Firefox on working and not working. That is very annoying as it means you cannot trust that you can continue doing things the way you were doing.
What I normally end up in doing in most actual situations is use chrome. I would like to use Firefox for such as I use for it for most, but...
But if you want to see your project in Firefox then you would likely need to get a real certificate. It is a bit more pain, but there are several free/very cheap alternatives.
