After I had auto upadte issue with Firefox this ,morning, and a manually uninstall of the 32 bit one, I installed a fresh 64bit install of 58.0. But if I go to one of my many web interfaces that use https: and have a self generated certificate , I go to add an Exception, If the "Permanently store this exception" is checked and I click the "Confirm Security Exception" button, nothing happens. If I uncheck "Permanently store this exception" and I click the "Confirm Security Exception" button, it works and I can get to my page. I have a number of Routers, switches, etc that only need self signed certificates, it will get painfull if I can't permanently allow the exception for these ones.
