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 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....

I was on the krogerfeedback.com site. Got finished and then went to kroger.com to load coupons for Friday. The page came up and said no coupons found try again later. maybe 30 minutes later can get to the site at all. I get this:

Secure Connection Failed

An error occurred during a connection to www.kroger.com.

It is not my internet causing it. I have been on you tube watching news clips and written a gmail to my sister while waiting for them to clear the error.

I hope I don't have to call their 800 number and talk to their helpless desk.

https://www.wrightbroslandscaping.com/ won't open, gives me "Secure Connection Failed" message. I want it to open anyway.

Error code: SSL_ERROR_INTERNAL_ERROR_ALERT

usually I am given the option to open it anyway, but not on this page.

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

I am trying to log on to Gordon Bernard Calendar Co once there I am informed that it is an insecure web site. I have been there many times. The GB web person says the prob. is on my end. My computer is old and I have always used version 7.

Please see below: for 2 instances that are occurring daily with firefox and should not be: firefox.exe attempted to establish a connection relying on an expired certificate to ads.mozilla.org

firefox.exe attempted to establish a connection relying on an expired certificate to ads.mozilla.org

It is a good thing that I have a good security system as Firefox is not doing its job. What is the problem? This is happening at least 60 to 100 times a day now. Kind Regards, Charlotte Sainz

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.

Kind Regards, Charlotte
