When accessing a website via HTTPS which has an untrusted certificate, Internet Explorer 9 always shows me the following error message:

Certificate warning

Is there a way to import the certificate permanently, so that I don't have to click away this message every time?

I don't have access to the root certificate the certificate was signed with.

Follow the instructions linked here:

It's pretty much the same for IE9, except you have to press the Alt key on your keyboard to get the menu bar to pop up.

I found I could not follow step 9, <<Click on "Certificate Error" at the right of the address bar and select "View certificates".>> Instead, I right clicked on the page, clicked "Properties" then "Certificates". That worked great. – Russell Silva Aug 29 '12 at 22:11
thanks Russell! I got stuck on the same bit – DevDave Nov 15 '12 at 11:01
This solution (installing the untrusted certificate into the Trusted Root Certification Authorities) is extremely problematic, security-wise. You are not adding an exception for a webpage, you are trusting the certificate for all reasons and purposes, including impersonating or your bank. – Mormegil Jun 15 at 12:51
