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.

I use Simplify.com to track some financial data but I cannot log in from the Firefox browser. I can get to the login screen but when I click login there is a spinning circle which never stops. I think I have found ways to put this in the exceptions but nothing works. I have a similar issue with Zinio.com. I can get to the website but cannot login. For both of these sites I have to use Google Chrome to get in.

Is this a new hack, or what?

I truly hope somebody can give me some help. I am struggling to understand why my website page containers go nuts on Firefox. I tried so much, I payed a good developer who told me the issue was over, but it is still there. I'm trying everything but my project is being a failure due to very nasty WP Theme issues, like this one. I had to spend my time fixing the Theme and my project completely past its deadline. Maybe I'm going to be fired, without fox.

I clearly cannot add site credentials for anybody, but maybe some developer knows what could be of help.

It seems that the issue has something to do with page Container and Flex attribute. The website is a Wordpress site and the page is built with WPBakery Visual Editor. All updated, no customizations, pages should work easy... As you can see the page title is ok, but then inside the main page container, the Visual Editor rows (which have display = flex) behave as if they had no width. Despite that, changing the flex attribute to display = block targeting FF specifically through Css, it doesn't seem to work either. It's not something simple just as a Row option inside the Visual Editor.

Please see attachments. Many pages behave like that. My questions: - is there a possibility to speak with Firefox assistance and get a clue? - did any developer from community, experience something similar before? How did you manage to solve it? - Firefox, why are you behaving like that with an old supporter?

Thank you to anybody spending his time to help.

The word "firefox" appears in the upper left corner of my screen and a "." appears under the app, indicating that it is open.
