I cannot connect to Social Media sites, YouTube, Google, any of my email sites, or even Mozilla.org using the firefox browser after the latest update.

"This Connection is Untrusted

You have asked Firefox to connect securely to support.mozilla.org, but we can't confirm that your connection is secure.

Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified."

It worked fine until I updated today, and I have to use Google Chrome to contact you. Please help me out, because going back to Internet Explorer would be a major letdown.

That's definitely not supposed to happen. When you see that page, it should have a sub-head that says "Technical Details". Can you click that, and copy what it says, and paste it here?

Date and time are correct. I have scanned with Malwarebytes Anti-Malware, and it found no problems. I tried some of the other suggestions that matched my problem description, and I am still not having any luck.

You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.

  • Click the link at the bottom of the error page: "I Understand the Risks"

Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".

  • Click the "View..." button and inspect the certificate and check who is the issuer of the certificate.

You can see more Details like intermediate certificates that are used in the Details pane.

If "I Understand the Risks" is missing then this page may be opened in an (i)frame and in that case try the right-click context menu and use "This Frame: Open Frame in New Tab".

  • Note that some firewalls monitor (secure) connections and that programs like Sendori or FiddlerRoot can intercept connections and send their own certificate instead of the website's certificate.
  • Note that it is not recommended to add a permanent exception in cases like this, so only use it to inspect the certificate.

So I'm supposed to do this for every single Https secure website I ever visit? Nope. F*ck that.

Hi RevKevK, this is to understand whether there is a global explanation for the problem. Sometime the company listed under "Issued by" is your security software vendor, and knowing that we can point to their procedure for trusting their signing certificate (or taking them out of the business of intercepting your secure web connections). Others are associated with malware and knowing that we can suggest what to remove. So please check at least one of them and report what you find or we can't assist you further.

This is happening to all my sites on Firefox, including this one. You Tube, Facebook and other sites I never had an issue with. I have to use Opera to connect to this page. Firefox is the pits

This is happening to me on THIS PAGE, Are you telling me Mozilla Support has a bad SSL cert?

Hi jakester, there are 3 common reasons to start getting SSL certificate errors on numerous sites:

  1. Discrepancy in the system clock, either date, time, or time zone
  2. Firefox not properly set up to work with security software that filters your web traffic (e.g., Kaspersky, Eset, BitDefender)
  3. Malware intercepting your web traffic

Our goal here is to help you figure out which one is the problem and fix it.

I suspect it's not your system clock, since that usually would affect multiple browsers, but it's easy enough to check that in case Firefox is more sensitive to it.

If you have added an exception for this site in Firefox, click the padlock in the address bar > More Information > View Certificate. Look at the "Issued by" section and reply with the name of the issuer of the certificate for this site. Often this will distinguish between #2 and #3, or it could be inconclusive, but either way, that is the next step.

If you have NOT added an exception in Firefox and are accessing this site using another browser, you can do the same check in that browser (the buttons may be a bit different, but start by clicking the padlock in the address bar and figure out how to view the certificate).

What do you find?

It isn't the clock, that is for sure I can't even get into this page in FF. Here is what it says when I try to access this URL This Connection is Untrusted

You have asked Firefox to connect securely to support.mozilla.org, but we can't confirm that your connection is secure.

If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

You will have to check the issuer of the certificate like posted above to see if that helps to identify the cause.

Are you talking to me? FF is doing it to EVERY SSL site, including this one. It gives the the exact same lying BS error message "mail.yahoo.com uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_issuer)" ON EVERY SITE! INCLUDING THIS ONE!

more options

Hi jakester, Firefox is just reporting on the certificate it is getting, which could be from the site itself or from some intermediary impersonating the site.

To get to the bottom of this "unknown issuer" problem we need to you to look at one or more certificates and tell us who is listed as the issuer. You've got some options in how you do this. Please see these earlier posts for more information:

An intermediary is impersonating every SSL site? That is total baloney. The same sites like You Tube come up fine in my 3 other browsers. And adding exceptions is not going to solve the problem either! I did it with You Tube and got about half it right since all the images and styles come from different domains. It won't even play a video. So that junks your "impersonation" idea.

Please, don't insult my intelligence. FF is DOING THIS TO EVERY CERTIFICATE. It is FF's fault solely, not any certificate issuer's fault For example, it says for Facebook: "Not specified" That is total nonsense. It is all FF's fault

more options

A possibility is that you have software installed on your computer that intercepts or monitors secure connections and places itself in the connection chain. In such a case Firefox gets the certificate from that software and not the certificate that is send by the website server. Because in such a case it is not possible to resolve the certificate to a built-in root certificate you will get the untrusted certificate message for each secure connection. If you do not check the certificate and tell us who the issuer is then we can't tell you how to proceed and fix this.

Hi jakester, it will take you 30 seconds to look at the certificate issuer, which I think is less time than continuing to complain that it doesn't make sense.

You can click the padlock in the address bar on YouTube, since you made an exception for that site. More Information > View certificate. Then see whether it matches what I get (screen shot attached).

There is no padlock Don't you understand, it does it to every site, including this one. it says there is no chain NO PADLOCK! NO PADLOCK! NO PADLOCK! NO PADLOCK! NO PADLOCK! NO PADLOCK! NO PADLOCK! NO PADLOCK! NO PADLOCK!

Hi jakester, I know that the error page doesn't have a padlock.

When you added an exception for YouTube, I would expect that you get a padlock, but you might also get a gray triangle with an exclamation point (mixed content warning). Click either of those to drop down a panel with the More Information button so you can access the View Certificate button.

If you don't get either a padlock or a mixed content icon on YouTube in Firefox after creating an exception, try checking the certificate in one of your other browsers that does show a padlock.

OKAY, there is a padlock on You Tube after I added the exception DO_NOT_TRUST But I can't even add an exception for this site. This Connection is Untrusted
