I am getting the below message when trying to log into the EFTPS site. I have never had this issue before.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.eftps.gov because this website requires a secure connection.

What can you do about it?

www.eftps.gov has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

I read the The Times in the UK and have no problem viewing on my iPad and Google Pixel phone using the Firefox browser. However on my laptop using Firefox I get a screen that says Secure connection failed and recommends contacting the vendor as there is no workaround. On microsoft Edge there is no problem I like Firefox but for me this is a major limitation. Any ideas or suggestions welcome

Can’t login to EFTPS.gov using Firefox and Login.gov. I receive an SSL error message.

Verified Firefox is rejecting 100% of all websites last few days and will not accept any Trust Certificates from Windows. Please correct and configure Firefox to Trust Windows Certificate store. Also is Firefox Mozilla using Windows DNS Servers , for security purposes ? Thank you Paul

Whenever I try to open Github specifically I get:

Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for github.com. The certificate is only valid for the following names: cloudflare-dns.com, *.cloudflare-dns.com, one.one.one.one

Error code: SSL_ERROR_BAD_CERT_DOMAIN

I spent time looking into this, used a new IP address and tried updating the certificate for github, however I'm not particularly skilled when it comes to this, so any assistance would be much appreciated.

I cannot get past the secure connection failed! I have cleared cookies, cache, etc. I have turned off the firewall, and restarted my computer more times that I can count....

You have not fixed the above where Firefox is attempting to connect to expired certificates!!!!!!! when putting the ads.mozilla.org in a tab it CRASHES...... You have a major security Breech taking place here. Please fix it with Humans and not AI responses.
