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
  The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
  Please contact the website owners to inform them of this problem.

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.

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?

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.

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.

"Secure Connection Failed

An error occurred during a connection to vi.vipr.ebaydesc.com. SSL received a record that exceeded the maximum permissible length. Error code: SSL_ERROR_RX_RECORD_TOO_LONG

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

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.

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.

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

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

 "the certificate is not trusted because the issuer certificate is unknown"

 "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

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

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

Secure Connection Failed + SEC_ERROR_REUSED_ISSUER_AND_SERIAL when accessing google

It's been a while now since I randomly started getting the above problem. I've tried the solutions described here: https://cheapsslsecurity.com/blog/troubleshoot-secure-connection-failed-error-firefox/ I've stopped the Kaspersky Internet Security, I've installed and re-installed Firefox, I've tried editing/deleting the damn security ceritficates, mothing worked. And nothing of Firefox's help pages... helped either.

I'm using the latest Firefox, latest KIS version, all the drivers are up-to-date, system (Win 7 64-bit) runs perfectly with no error whatsoever, same for the Inetrnet connection. At this point I'm just about ready to flush Firefox down the drain because of this frustrating problem. It will probably go away after restarting the system, but I don't want to do this at Firefox's notice whenever it feels like it. I just want it to go away period.

Since it looks like it's impossible to attach a simple .jpeg to this message (file keeps loading forever), here's the full text of the error: "Secure Connection Failed An error occurred during a connection to www.google.com. You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number. Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem."

Side note: very funny having to confirm this question by checking my gmail address... which I can't access because of the reasons stated above.
