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.

Attached is a sample of how web pages display. These can either initially display this way or, as in this example, the page opened correctly, I stepped away for a few minutes and when I viewed the page again it looked like the example. I can have a page open and it is displaying correctly, then open a new tab and go to a different site and the text will look like the example.

I have cleared the cache, dumped all the cookies. Restarting the browser (I do this many times a day) will fix the current page but eventually another page will display like this.

I running version 84.0.2 64bit on a Mac Pro Mojave. I don't have this problem with other browsers like Chrome or Safari. I never see it on my Windows 10 system.

My Firefox has started refusing to open certain websites which I have previously accessed. These include, but I suspect are not limited to: warhorn.net foambrain.com mybestjudymerch.com

Google Chrome on this computer will open these sites, as will my Firefox install on my work computer. I'm running Big Sur 11.2.1. I have tried every step on https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can and https://support.mozilla.org/en-US/questions/1290042

Hello everyone

This issue started today 10/March/2021 and only on Firefox. I have tested this into 4 different computers and it only occours on Firefox, other browsers are fine.

As I try to perform any search on Youtube searchbar, spacebar wont work. It acts like it is pausing/unpausing a video, and does not "space" the words. In fact, all Youtube shortcuts seems to be "live" even when a video is not playing

Any other site its working fine.

Anyone got any ideia on how to solve this issue?

Thank you

Hello everybody,

There are more and more websites that have functions that no longer work with Firefox and force me to use Chromium instead. Do you if there is any chance that an upcoming release will put everything right?

Thank you in advance Virginie

Hello.

The website in question is https://www.liverpoolfc.com/ and the more specific pages with this problem are the sub-pages of the Competitions page.

Main page: https://www.liverpoolfc.com/fans/competitions

Some examples of sub-pages: https://www.liverpoolfc.com/fans/competitions/win-a-jota-shirt-and-lfc-ball https://www.liverpoolfc.com/fans/competitions/win-a-jota-shirt-and-lfc-ball

I have tried the solution where I cleared my cookies and all the saved data. The problem still persists. But if I use any other browser, the content loads correctly. With Firefox on the other hand the content doesn't load - or it loads but it doesn't display?

Anyone has a solution? It's a very frustrating problem. I have asked LFC for a solution but they said that they cannot replicate the problem and they just simply suggest that I use a different kind of browser - I don't want that, because I love Firefox.

I have attached some snips of how the pages look in Firefox, Edge and Chrome.

Thanks in advance.

Hi,

I'm new to firefox, I'm trying on this new linux based config to change from chrome to firefox, and I've got an error on most of the different website I'm trying to join : "Hmm. We’re having trouble finding that site." For short it's the server not found error, but I can access thoses websites from an other browser.

I'd like to solve this problem, I already tried ipv6 disabling, and dns prefetching enabling from this help page : https://support.mozilla.org/en-US/kb/server-not-found-connection-problem and it still not resolve my problem.

It often resolve alone half an hour after I started firefox, but it is way too long...

Thanks a lot for helping me !

Matthieu

PS : domains I can't access : github, my school website, youtube sometimes...

Like many users, I find Google's 'before you continue' pop-up annoying. Because I automatically delete cookies on browser exit, it keeps popping up as it doesn't remember my settings. I have installed Google Consent Dialog Remover, and it has been working well... until now.

I just did a search for a place, and tried to click on the map to go to Google Maps. The dialog intruded, despite the add-on. But worse than that, when I clicked 'I agree', nothing happened! I cannot get to the maps page at all. I've tried disabling enhanced protection -- no change. I've tried disabling various add-ons -- no change. I've tried restarting FF in safe mode, but the same problem persists.

I can't figure out how this is happening or what to do about it. Any suggestions?

Thank you!

I found out that menu with image items appeared not only on selected images but on web site's background image. I believe that in previous version of Firefox this menu did not appeared on background images. Moreover I saved a web page and opened it. Link to this background image could find on style.css file only. I checked list of files for saved web page and these images are not exist. Therefore if this web site will be shutdown I would not be able to open saved page properly. It is interested that when I click on saved web page items of this menu appeared. When I select background image to try to open in next Tab I get a message that this file is not exists off-line. Yes, file is not exists but but Firefox saved link to background image not an image itself.
