Secure connection cannot be established When a website you visit attempts to secure communication between your computer and the website, Firefox cross-checks this attempt to ensure that the certificate and the method the website is using are actually secure. Some websites try using out-dated (no longer secure) TLS mechanisms in an attempt to secure your connection.

So, when I type https://localhost/ and click on Get Cert. button, the Alert message popups and it disables the checkbox for Permanantly... and "confirm security exception" button too. Need help imdly.This is really frustrating.ReplyDeleteKittyJanuary 21, 2010 at 9:54 PMHello, I am getting this for all sites, even the Mozilla/Firefox website and have to click add exception on every page.
