Why is access to this site being blocked all of a sudden? I have been subscribing to this online newspaper for decades, and now within the last month I cannot load the page because of a security problem. Why is this happening? There is nothing wrong with the site.

An error occurred during a connection to www.netacad.com. The OCSP response is not yet valid (contains a date in the future).

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

bold text I use Firefox in many years, but the last 3 days it is impossiple to come to my mail by dandomain.dk (got it in many years) and it never apears - and when I ask, some write: security risk!! and what next :-((((

Bitdefender security software Online Threat Prevention "Notifications" are blowing up stating the following: "firefox.exe attempted to establish a connection relying on an untrusted certificate to incoming.telemetry.mozilla.org"

The issue began approximately 17:00 UTC November 16, 2025

Please investigate & update the certificate or we may need to move to a different browser.

One morning could not connect to email/ATT. This is the error message I got: Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over. ATT came to home to look into hookup, etc. Could not fix. They advised Firefox could be corrupted. Should I reinstall Firefox. Had to go thru Chrome for email. Have Windows 11. Thank you.

I am getting a Secure Connection Failed error on every webpage I try to visit. Even if a page manages to load it will revert back to the Error code: PR_END_OF_FILE_ERROR if I refresh. Other browsers are working fine. I tried troubleshoot mode and it's the same. I tried uninstall/reinstall, desktop restart and still the same. I haven't changed any settings on my mac.
