SEC_ERROR_UNKNOWN_ISSUER for Google and Youtube

I am getting a certification issue when trying to visit 2 specific sites which are some of the most visited sites in the web: https://www.google.com and https://www.youtube.com

The error it shows when trying to visit these 2 pages, is SEC_ERROR_UNKNOWN_ISSUER.

I have tried to troubleshoot it and follow the solutions recommended at: https://support.mozilla.org/en-US/kb/error-codes-secure-websites#w_the-error-occurs-on-multiple-secure-sites

however none of the solutions described in this guide worked to solve my problem.

In that guide, one of the suggested solutions is to scan my system for any malware. I used the following: Windows Defender Maleware Bytes AntiMalware Karpersky TDSSkiller however the results are all clean.

In the guide, it suggested that I check the clock as well. The system clock however is synchronized.

Last, I have resetted Firefox Profile but this didnt fix the issue either.

I shall note that the issue appeared yesterday and so far nothing helped fixing it. Not even the system restarts.

The issue about visiting these two sites, is limited only to Firefox.

I can access https://www.google.com and https://www.youtube.com without problems using Google Chrome and the Opera Browser.

Also, Google Mail and Google Translate work fine on Firefox. These two sites can be accessed with Firefox without causing any SEC_ERROR_UNKNOWN_ISSUER errors.

Reviewed "Sheribee" earlier issue which apparently involved a VPN. I do not have a VPN but have tried several times in the past week to access IRS refund status site without success. I can get into irs.gov, but am unsuccessful in accessing the refund status site after entering required input data. The issue has occurred only this past week.

I'm unaware of IRS issues causing this problem.

Have not had this issue on any other sites; and I have successful retrieved data in prior years.

I am not saving any sign on protocols with the irs or any other sites.

Running Windows 10. Thanks for any help. BTW I did get refund information using the telephone, but I want to ensure there's not a hidden conflict of some sort with FireFox. Thanks for any help.

Hi all,

while playing (or better "fighting"...) with a linux docker container on Win10/WSL2/Ubuntu for using the MS spfx tool chain, I generated a SEC_ERROR_REUSED_ISSUER_AND_SERIAL in FF85.0/Win10 by first setting up a certificate exception for a dev-cert (https://localhost:4321) and then have the certificate re-created.

As described the support article [https://support.mozilla.org/en-US/kb/Certificate-contains-the-same-serial...], I removed all certificate exceptions for localhost:* and deleted the "gulp" authority in options/security/certificates.

Unfortunately, the SEC_ERROR_REUSED_ISSUER_AND_SERIAL persists even after a restart of firefox.

Any help is very much appreciated...

I'm on firefox 90.0.1 on Mac OSX Big Sur 11.2.3. When I try to delete a site certificate that I have (that is about to expire), it appears deleted, but when I open the certificates page again it reappears. When I restart Firefox after deletion it reappears. When I delete cert9.db from my default profile after closing firefox, and then reopen, it still reappears. When I uninstall Firefox, delete the default profile folder from App Data and the Mozilla and Firefox folders from my caches, it still reappears (I also deleted the update folder).

I am doing sync between this mac, my phone, and another computer, but I ONLY have bookmarks, Add-ons, and history. Might the sync be also syncing my certificates?

Help/tips would be appreciated.

Edited to add TLDR: some Firefox requests to Google servers seem to fail internally. What can I try to diagnose the problem?

I'm having a recurring problem with Firefox on various Google sites: google.com, Gmail, Calendar, Keep etc. For long periods of time (but not always), Firefox completely fails to load the site, or loses its connection after the page is loaded (for example Gmail displays an error message "Oops... The system encountered a problem (#001)"). The problem usually seems to occur for periods of many minutes, with occasional gaps where the sites work properly. Also, it seems to be site-specific: sometimes it will load google.com normally while Gmail is still having problems. This is really frustrating, I'd like to use Firefox for all my browsing but I also need to use Google services regularly and that doesn't work if Firefox won't load them properly most of the time.

I'm pretty confident it's a problem with Firefox itself, and not with my network or computer, because I get the same issue across multiple Firefox installations and versions (Firefox 90 and 91 on Windows 10, and Firefox 78.10.0esr and 90 on Linux), and while the problem is happening I can access the same sites successfully from a different browser on the same computer (Chrome or Edge). I've tried refreshing my Firefox profile, working in a private browsing window and using a completely new profile, but the problem still occurs. I've also made sure I'm using "Standard" protection in Firefox's security settings and disabled Enhanced Tracking Protection for the sites I'm trying to access.

I've tried to look at what's going on using Firefox's Network Monitor, and the key thing that seems to happen when this problem occurs is that one or more network requests to a google address (google.com, mail.google.com or ssl.gstatic.com) appear with "0 B" in both the Transferred and Size columns (see screenshot attached). Sometimes the failed network request has a simple padlock icon as in the screenshot, and sometimes a red error symbol with mouseover text that says a security error prevented the resource being loaded. There's also occasionally an error message in the Console: "A ServiceWorker passed a promise to FetchEvent.respondWith() that rejected with 'TypeError: NetworkError when attempting to fetch resource.'.". Removing the relevant service workers in about:serviceworkers doesn't make any difference. On Linux, I've tried using tcpdump to check the actual network traffic and it looks like nothing is actually sent across the network for these requests, so whatever the problem is seems to be happening inside Firefox itself.

Ticking the "Disable Cache" box in the network monitor doesn't help. If I manually resend the same request using the menu in the network monitor, a normal response is received (but the content is not actually displayed in the browser).

It looks to me like some kind of caching or security problem, where Firefox somehow gets in a state where some network requests are blocked or fail to load from a cache, but after a while whatever is causing the problem is cleared and it works normally for a minute or two before the problem recurs. I would simply report this as a bug on Bugzilla, but I can't offer steps for anyone else to reproduce the problem because it only happens when I'm logged into my own Google account. I've run out of ideas for how to diagnose or fix this. Can someone suggest anything else I should try? Thanks!

I hope someone can help me with this problem. I own the domain "cpaaffiliatesnetwork.com" and the site serves as my business site and access to my business network platform. The site is SSL secured and the SSL certificate was renewed in February 2021 for 1 year. Since the SSL renewal, I started having issues accessing the site from any browsers installed on this computer (Edge, Firefox & Chrome). I have now managed to fix the display issue in both Edge & Chrome through clearing cache / history, BUT, I have tried the same with FF with no success. I have also tried uninstalling and reinstalling Firefox, but, still receive the error below for any attempt to access the site: Secure Connection Failed

An error occurred during a connection to www.cpaaffiliatesnetwork.com. Peer’s Certificate has been revoked.

Error code: SEC_ERROR_REVOKED_CERTIFICATE

   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.

All external people i have asked to check the site have confirmed it works fine for them, but, it will not work for me. Hoping someone has a suggestion many thanks in advance :)

This started happening on many websites this week. Sometimes refreshing the page helps, sometimes it doesn't.

I'm only using Windows Defender and Tinywall (blocks everything through windows firewall) as security.

After auto update to FF 89.0, access to long-time Fidelity account is intermittently blocked as a security warning, or causes DSL line to drop at submission of account security code, or displays account entry page as plain text, not std HTML formatting, or most often results in a technical error page saying try again later. MS EDGE works fine, no issues. This is the only webpage this occurs on. Fidelity has no FF reported issues on their end nor does my IP supplier. Using desktop PC, running Win10/64-bit, DSL line @ ~ 2.3 Mbps. Using the "Light Theme" which was auto set with 89.0. This plus the new bastardized menus will push me to drop FF since I can't afford endless hours to fix basic functionality with ea update.

I need to download a certificate from a device in my networt called secunet Konnektor

https://www.secunet.com/loesungen/einboxkonnektor

on the manual it's written how to do it.

https://www.secunet.com/loesungen/einboxkonnektor#c1607

I suggest to find a manual somewhere in the first link or in google:

chapter 7.4.3

go to chrome (same with edge)

click on the lock on the left hand side of the link https://XXX.XXX.XXX.XXX:8500/management

somehow click on the button where you can open a small windows called "certificate".

The "General" tab shows informations about the certificate.

Click on the tab "Details" and click on "Copy file".

The certificate-assitent opens and after clicking on next, you choose DER-coded-binary X.509 (.CER)

Save the file somewhere where you can find it.

I can't do this on firefox

On firefox I can find a lock on the left hand side of the link https://XXX.XXX.XXX.XXX:8500/management

when i click on it and then on something else, i can then click on more informations.

under "security" i click on "view certificates" and a new tabs opens called "certificate for konnektor".

but there is no possibilty to download a cer-file. only a pem file and it doesn't really help me.

Hi, I've been having issues with Firefox for some time now. Every page I got to throws a NS_ERROR_NET_INADEQUATE_SECURITY error. I cannot fix it by setting network.http.spdy.enabled.http2 to false is because Firefox then starts crashing. In the past I've gone around the error by turning http2 off, but recently, first the developer edition, then after today's update to 91.0-0.1 of stable version Firefox crashes if I turn the feature off.

The developer Edition started throwing NS_ERROR_NET_INADEQUATE_SECURITY sometime in spring, then started crashing in June I think. The stable version followed soon as described above.

I am submitting this ticket from a beta version, which for some reason does not have this issue.

I thought it may be the Linux version of Eset, but removing it did not help. I cannot think of any other reason why am I getting those errors, but it seems I am alone because my colleagues don't seem to have this issue neither on macOS, nor Windows.
