I am trying to access static IP addresses on my Intranet. I could in the past type in the IP address and I would get a notice that the site is not secure and allow me to continue to the site. Now it tells me that the website cannot be reached. I need to get to the GUI interface of cameras on my network. How do I get this to work?

Hello Mozilla Support, I am getting Error 526 when I try to open YouTube in Firefox. Other websites work normally, but YouTube does not open. I have already checked my internet connection and restarted Firefox, but the problem still exists. Please help me fix this issue.

All of a sudden almost every site I try to enter comes up with "Secure Connection Failed". This started happening on Friday, July 10th for the first time. I've read almost every article in the Firefox's community forums and tried multiple actions and nothing stops this. I don't know why this all of a sudden when it never did this before. I hope someone can tell me how to stop this from happening].

Your computer thinks it is May 1, 2026, which prevents Firefox from connecting securely. To visit www.olx.com.br, update your computer clock in your system settings to the current date, time, and time zone, and then refresh www.olx.com.br.

Secure Connection Failed

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

Secure Connection Failed

Be careful. Something doesn’t look right.

Firefox spotted a potentially serious security issue with ebanking.bankmellat.ir. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails.

ebanking.bankmellat.ir 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 browser prohibits access to the social network https://vk.com/ . The browser leaves a response: "Firefox has discovered a potentially significant security issue id.vk.com . Someone impersonating the site may try to steal data such as bank card details, passwords, or email addresses".

It used to be possible to proceed if I clicked on "Advanced", However, I can no longer do this with the latest update of Firefox. It's this site: link text

I am getting more frequent "Firefox can’t create a secure connection to the server " messages. This isn't inherently an issue, but on most of them there is no longer a "continue anyway" button. I know your first response will be "It's for your safety." Well now, I'm a big boy, 58 to be exact, and I wear my big boy pants everyday. I am perfectly capable of deciding how much risk I'm willing to accept. This especially applies to sights I am familiar with and trust that suddenly trigger your warning for some mysterious reason. This is becoming a large problem for me and if there isn't a fix for it I may have to reconsider my use of Firefox.

성인사이트가 크롬과 엣지에서는 정상적으로 열리는데 파이어폭스에선 보안 연결 실패라고 뜹니다. 원래 파이어폭스에선 성인사이트를 차단하고 있는 건가요? 아니면 차단을 해제할 수 있는 방법이 있는 건지요 Adult sites open normally on Chrome and Edge, but on Firefox it says security connection failure. Is Firefox originally blocking adult sites? Or is there a way to unblock it

Hello!

For few minutes it says "Performing a TLS handshake to youtube.com", then this message appears:

Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

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.

What I did so far:

1. Deleted cache and site data for youtube.com. 2. Checked if date and time setting is set to auto and synced it just in case. 3. Tried restarting firefox in safe mode. 4. Tried turning off ocsp stapling. 5. Deleted ALL cache and site data. 6. Tried creating a new profile. 7. Set HTTPS-only mode to "don't enable" and added youtube.com to exceptions

I do use DoH. I can't not use it. YT won't work without it for sure. Provider is google: https://dns.google/dns-query

Everything works fine in Chrome (yes, I use DoH there too).
