I have never ever had a problem getting into my bank account until this evening.

Says it is insecure.

How can this happen? I really need to get into my account!

Hello,

I have been using Firefox for many years and also have Bitdefender Security Premium running on my devices. Unfortunately, I am getting more and more messages like the following:

Function: Online threat protection

firefox.exe attempted to connect to ads.mozilla.org using an untrusted certificate. We blocked the connection because untrusted certificates are issued by unrecognised certification authorities.

However, I can confirm that Firefox and the add-ons are all up to date. But I also trust Bitdefender, as this message will not have come out of nowhere. What can I do to get everything working properly again? Thank you. Kind regards, NaIch

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?

'I was sent a link that goes to a learning site by my future employer to take some online classes via email. Every time I try to access the site I get a message that I need to close the page as the website may be impersonating someone trying to steal my information. I use Safari, not that I have a clue what it means, is this a restriction issue I need to avoid or sidestep like a firewall or something similar? I tried typing the web address and the HR office says not to do that - to only use the link. How can I check what’s wrong so that I can take access the online classes for this position?

Did Not Connect: Potential Security Issue

Below mentioned issue occuring ???

Firefox detected an issue and did not continue to finance.jharkhand.gov.in. The website is either misconfigured or your computer clock is set to the wrong time.

It’s likely the website’s certificate is expired, which prevents Firefox from connecting securely.

What can you do about it?

finance.jharkhand.gov.in 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. You can notify the website’s administrator about the problem.

when I go into firefox and enter my password this is what I see.

It seems lately that about 40-60% of the links I click on do not work while browsing on Firefox. Most of these are links from trusted sources, many from subscriptions services I'm paying for, and thus unable to gain access to. I will get an error message saying something like "secure setting failed," or something similar (see attachment). Is this something new added to Firefox for added security? And I read some solutions in the settings area, but it seems like most of them can't be bypassed. It's very frustrating because many of these links have valuable info or tools that I can't access. Do you have any advice other than to contact the sender (which rarely results in a solution)? Thank you, Paul Fernandes
