My browsers are not displaying the http://superuser.com website as they should.
When I go here in IE, it renders incorrectly (my guess is it renders without CSS); then IE displays a message
Internet Explorer blocked this website from displaying content with security certificate errors
I click on "Show content" and everything looks OK. Web is colored and rendered as expected. In Firefox I have the same issue but can't find any option/settings to correct it. I check many other web sites but everything looks OK.
Reset Firefox preferences "https://support.mozilla.org/en-US/kb/reset-preferences-fix-problems"
And Add Exception "http://www.andrewlucking.com/archives/2007/10/secure-connection-failed/" for "http://superuser.com/"
I have: Win7 sp1 64-bit, Firefox 22.0, IE 9
