Hi guys!

First, I use Internet Explorer. Today, I have installed Mozilla Firefox in my computer system. Now, I am trying to open any site through Mozilla but it is not working. When I press ENTER, I received untrusted error. I am very confused about this error. Can anyone provide me a detailed solution?

Mozilla Firefox-This connection is untrusted

This connection is untrusted
 
You have asked Firefox to connect securely to isc.sans.org, but we can’t confirm that your connection is secure.
 
Normally, when you try to connect secured sites, you will be asked with identification to prove that you are going to the right place. However, this site’s identity can’t be verified.
 
What should I do?
 
Usually, when you connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn’t continue.
 
Get me out of here!
 
Technical Details.

If Firefox could not verify the certificate, it will show that error. This only happens when you visit a secure web site. That means, having an address that starts with https. The warning tells you to be careful because the site may be unsafe for eavesdropping. If you know the site, there is no reason to be stuck in there.

You can bypass it by choosing the “I Understand the Risks”. Add the exception and confirm the security exception. You also have the option to permanently store the exception if you know the site by ticking the checkbox button that says “Permanently store this exception”.

http:// is different from https://. 
 
Http is the abbreviation of Hypertext Transfer Protocol which is some rules regulating the transfer of different types of file including sound, graphic, text, video, and any other types on world wide web.  
 
Https is the abbreviation of Hypertext Transfer Protocol Secure which is the secure version of http.
Https shall be used whenever there is secured transaction on web e.g. online banking so that the website encrypts the transaction with a digital certificate.
 
This digital certificate will help the browser to decide if the website is genuine.
 
There will be an alert if the digital certificate has any problem.
