" The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported."

"(Error code: sec_error_unknown_issuer)"

what do i do with this error ??

I'm still getting the "Secure Connection Failed" error on various sites.

Only in Firefox. Internet Explorer and Chrome both load the sites correctly.

Tried to connect to https://www.ghacks.net/2016/12/19/remove-g-button-android-keyboard/

  An error occurred during a connection to www.pcmag.com. Peer received a valid certificate, but access was denied. Error code: SSL_ERROR_ACCESS_DENIED_ALERT

Restarting in safe mode does not fix the problem.

Changing security.tls.version.max and security.tls.version.min to 0 and restarting does not solve the problem.

Trying with a new profile with no extensions or other changes from the default had no effect.

Firefox 56.0b7 (64-bit) for Windows.

I receive this error message when trying to access a military course online. I have tried everything I can think of to troubleshoot this, including your online suggestions. Please help me to disable this error message and get past it. I trust the website I'm going to, https://ellc.learn.army.mil. I don't need anything protecting me from this .mil website that's required for my work. I sent in this question before, and got no response. Please help.

There are several hundred browser websites that are opened after reboot with Mozilla Firefox reload.

How did this happen with a reload?

Is this a cache or cookie problem?

What was changed in the January Mozilla Firefox update?

Ccleaner requires that the browser is closed to clear cache and cookies.

If this were done the several hundred webpages would no longer reopen.

How can the Mozilla Firefox browser be modified so that it no longer displays Access Denied without losing the reload option for the hundreds of websites that are currently open?

(The browser typically has the default settings)

The Google Chrome and Internet Explorer browsers can open these websites without problems. Other end users opening the same websites with Mozilla Firefox did not see Access Denied.

For this problem please indicate:

What specifically happened with the January update that may have caused this problem? If it was not the January update what else could have caused this problem? How can the problem be fixed so that the webpages that are currently open can easily be reopened after a reboot with reload? What could have been done to prevent this Access denied problem?

A webpage on our internal company domain ("") errors out with "Error SSL_ERROR_RX_RECORD_TOO_LONG". If I switch to private browsing the same page works. The page also works with all other browsers without issue. If I "reset firefox", the page starts working again - even after firefox sync has re-installed all my add-ons. After some indeterminate amount of time (weeks) the page starts to error out again. This problem occurs on Firefox 75 on Ubuntu 18.04 as of now.

I'm at a total loss as to how to even begin to debug this - any pointers on where to start looking? As I mentioned the webpage that errors out the only page on an intranet so I cannot share the URL.

How do I disable the warning screens that say "Warning: Potential Security Risk Ahead" when I visit sites on my home network (192.168.1.0/24)? Nothing I've tried seems to work. Thanks, Eric

I have been using firefox since beginning of 2003, yes I pretty sure you know what that means. Now I understand that SEC_ERROR_UNKNOWN_ISSUER is a add security feature (okay some people need that) But 90% of the ppl using FF, does not need that. Since I can not turn off that feature, you are violating my net neutrality. You are telling me what websites I can go to, and can not go to. FF went from a slim active Fox, to a out of shape bloated pig. I never thought I would see the day when a Microsoft browser was better FF. Edge is crushing you all stat wise, you are not even on the same playing field.

We recently renewed our wildcard certificate, however 72 hours after the re-key was done to get a new Private Key, we started getting this error and similar ones on other browsers, this seemed to clear ok on other browsers except for Firefox. We had further issues with our website and the Cert was re-keyed again, downloaded and installed based on Apache and that seems to have resolved it again, however when trying to access our cloud based Mitel console it is still throwing this error up but it is working fine in all other browsers. I have cleared Cache, refreshed Firefox and deleted the cache9b database file all to no success. Not sure why this is causing so many problems. Anyone out there that can offer any assistance? Many thanks Barry

Once or twice a day since using my new computer a couple of weeks ago, just while generally browing around the internet, virtually every page that uses 'HTTPS' suddenly stops working. Firefox claims the certificate for the sites aren't recognised and gives the SEC_ERROR_UNKNOWN_ISSUER message. Even the https://support.mozilla.org/ pages become inaccessible because they're https as well. Nothing I've come up with can fix this except restarting the machine, which fixes the issue immediately and every site starts working again.

If every https site was constantly blocked, I'd assume it was just my security software's settings and try to change them, but it's weird that the issue pops up occasionally at seemingly random times. Any ideas? An example of the error message and Advanced details is provided below. Apologies that it's not formatted quite as on the original page.

since after Firefox 59. All my existing passwords have gone awol (settings passwords blank) and no new passwords are being prompted to be added even if I enter them in websites. (also wierdly since 59.01 it keeps a restart message in the help even though i have updated

Firefox automatically updated itself and installed "Firefox Quantum" 60.0.2 I see - 64 bit - on Windows 10 on a Dell laptop.

Never had this problem before - but when loading Ebay pages, the main body of the advert page fails to load and the full message I get instead is below - I've tried switching the proxy settings to "No proxy" or "Use system settings" and sometimes page loads correctly once but then it fails again! Have cleared cache/cookies, have refreshed, have restarted ...

Very frustrating and this is about to lead me to give up finally on Firefox and move to Chrome.

Dear Mozilla I have encountered the "SEC_ERROR_UNKNOWN_ISSUER" error when trying to access google.com Unfortunately, Mozilla Support sites only explain the origin of the problem. No solution to solving the issue is given. I can't even proceed to the website accepting the risk. I have found other pages with suggested solutions but none worked. I tried deleting the Cert9.db file which didn't work. Other solution are for antivirus on windows which doesn't help since I run Ubuntu with no antivirus. I'd greatly appreciate any help. Thx in advance

Every day around 9:30 PM, browsing the web becomes impossible. nearly every site I visit brings up a This Connection Is Untrusted page. I have tried using different browsers and Different Devices. Even my 3DS doesn't work. This has lead me to believe that the problem is either with the modem or my service provider. I checked the certificate of Google via chrome://pippki/content/exceptionDialog.xul, and it read ISSUED TO Common Name (CN) security.frontier.com Organization (O) security.frontier.com and when I checked it now, it reads ISSUED TO Common Name (CN) www.google.com Organization (O) Google Inc I don't know what fixes this problem since the problem stops at different times. It started around when I installed AVG, so I tried uninstalling it, but the problem didn't stop. While I'm fairly certain the problem isn't related to Firefox, this is one of the sites that I am able to visit when this problem occurs. I have tried manually adding the exception so I could bypass the Untrusted Connection page, but the page never loads and the next time it happens, the page is there again anyway.

Tried to access my online bank account from your website but got a message that it's not a secure site. I called my bank who told me that it's because of one of your updates. How can I fix this issue? I can access my account from other sites, just not yours.

Keep getting that error on several sites (Facebook, Youtube, etc), although I unistalled the latest version I had on my PC, and installed an ESR version (52.5.3). Any change to get rid of such annoying error ? Thanks AC

Hi everyone,

on my Dell laptop I suddenly started getting a PR_CONNECT_RESET_ERROR a few days ago when trying to access websites like google, facebook, youtube etc.

Other websites like ebay, amazon or tripadvisor work. The problem also occurs with Chrome and IE.

I have checked date and time, run all troubleshooting programs, restarted router and laptop, cleared cache and cookies and deactivated the windows defender firewall. I have no other security software installed.

Now I am all out of ideas. Can anyone help?

Thanks Kim

So far I get the following error only when trying to go to

Https://www.Google.com  ""SEC_ERROR_UNKNOWN_ISSUER" and it will not let me add an exception .

Hi there,

We have a weird problem with firefox only (not this problem with other web browser like Chrome, Ie or Edge). The problem is that we cannot browse this website at the same time. No problem to browse one website, but going on the seconde one and you will get on 404 error.

Not Found ________________________________________ HTTP Error 404. The requested resource is not found.

Same error for 3 others.

Just waiting few minutes (at least 5min), refresh the second website, it’s working coming back on the first tab (with the first website), refresh and you get the error 404.

This problem occurs only when we are using IPV6 connexion on an HTTPS websites (only on some of ours web sites (https://www.ticpharma.com/home.php, https://www.techopital.com/ https://www.gerontonews.com, https://www.ticsante.com/home.php and https://www.apminternational.fr/). These 5 website sharing the same SSL certificats. It’s a multi domain SSL certificats provide by Gandi.net.

No problem when we use the Firefox PRIVATE windows. No problem when we browse theses websites in http and IPV6. No problem when we browse theses websites in httpS and IPV4. No problem with other browser in httpS and IPV6.

So only problem with Firefox, in IPV6 and HPPS. This problem occurs on multiple computers, with diffrent Anti-Virus, from different location, for different network and ISP provider. So I guess there is a bug somewhere in firefox.

Thanks for your help. Regards.

The problem exists since yesterday. Today I repared Mozilla. After this the problem first does not exist anymore, but less hours later the problem is here again. My Firefox is not too old. I use Firefox Quantum.

Hi all, I'm using Firefox 39.0. When I try to connect to our web site, (which has a RapidSSL certificate installed) it shows the errors;

 "the certificate is not trusted because the issuer certificate is unknown"
 "the server might not be sending the appropriate intermediate certificates"
 "An additional root certificate may need to be imported"

If I look at the certificate chain I get the information below; Under the issued by, I have

 RapidSSL SHA256 CA - G3
 GeoTrust Inc.
 <Not Part Of Certificate>

When I go to the site with IE, there is no security warning. Any help with this is greatly appreciated.
