Hello, I run a movie and drama-related website: https://tvmon.com.co/. Recently, I’ve noticed that Firefox occasionally throws the following error when trying to access the site:

"Secure Connection Failed An error occurred during a connection to tvmon.com.co. . The OCSP response contains an invalid signing certificate. Error code: SEC_ERROR_OCSP_INVALID_SIGNING_CERT"

This issue is very strange because:

  1. The site loads fine in Chrome, Edge, and Safari.
  1. My SSL/TLS certificate is valid, up-to-date, and passes external tests (SSL Labs, etc.).
  1. The error only appears occasionally in Firefox, refreshing sometimes fixes it, sometimes not.
  1. Hosting and server logs show no issues at all.

I suspect this is related to Firefox’s stricter OCSP validation, but I’m not sure how to debug or resolve it. Since my site streams drama and movie content, this error is frustrating for users who rely on Firefox.

Has anyone else experienced this intermittent OCSP signing certificate error? Is there a known fix or workaround for Firefox-specific validation issues?

My cat jumped on my keyboad and Firefox detected 'unusual activity' She probably hit a combination of keys which lead to said activity. Instantly, I had to verify whether I was a human. I did, but really, it was my cat. Neither my cat, nor myself have bad intentions. I just thought Firefox security should know that these things might happen.

I hope that my cat's activity didn't compromise my account. Maybe 'unusual activity' should be less strict, though I do understand that Firefox must be vigilant. Maybe it would be a good idea to let users describe what happened, before sending Captcha?

Hi

I had to uninstall my VPN because it was frozen, and I couldn't even switch it on, even when I restarted my computer.

This has happened before, so I had it uninstalled & then downloaded it again.

You will see proof, by the screenshot I have attached to this email, please advise manufacturer.

My OS has the latest updates MacOS Monterey 12. 7. 6

Kind Regards

Joe
