I periodically need to access a website with an expired or self-signed certificate. I understand the risks, but the browser won't let me. I've searched both the regular settings and about:config, but I can't find an option to restore the button to ignore the warning. How can I ignore the SEC_ERROR_BAD_SIGNATURE notification and proceed to the website I need?

Здравствуйте! Не могу перейти на официальный сайт поликлинике "http://18pol.city.kharkov.ua/" чтобы срочно записаться на прием к врачу. Браузер Firefox постоянно выдает ошибку " Будьте осторожны. Что-то выглядит не так.". Сайт безопасный и официальный, но браузер все ровно не дает возможность перейти.

‘Firefox is blocking me websits or torrent sites because the certificate is outdated I have no option to carry the risk an acces it!!!’ This is disgusting!! Many good websites habe no certificates. It is obviously used as censorship. What can I do? I used the Testa del Rutor terrent

Hi, I try to use Firefox for my job and faced with the problem that I can't open state owned website due to sertificate signature error. I ready to take a risk but I can't find the button "Proceed.. (Risky)". This button simply not showing. In th same time in mobile version I saw this button, could take permssions myself and open the website. I tryed to add root and sub sertificates of the Goverment, tryed to add the site address to exclusions -- all these steps don't work. I can't open the site and can't find button "Proceed.. (Risky)". Moreover, in the same time, I can open this website without any questions and problems with Safari and Chrome.

I use the last Firefox version (153.0) from Firefox official website.

How can I resolve this problem in Firefox? Please help me

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.

After updating software and restarting my laptop (Lenovo running windows 10 or 11) Firefox now displays this message for every web page (this example from attempting to access Gmail, but same message with all other sites I have tried):

"Be careful. Something doesn’t look right.

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

mail.google.com 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."

I now can't access any pages using Firefox. Long term user, so I hope you can help me! C

I am trying to access my QNAP NAS configuration page within my home LAN from a newly installed Linux PC with Firefox 147.0.1. Firefox won't let me access the page, popping up an error page:

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to nessy.fritz.box. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

I have verified that the claimed risk is nonexistant, but Firefox does not allow me to bypass the warning. There is no "Proceed anyway" or "Advanced..." button as claimed in various help articles.

How can I convince Firefox that I know what I am doing?

NB: The same page is accessible, also with Firefox 147.0.1, from a Windows PC.

I can't bring in www.facebook.com so I can "sign-in" to my FaceBook account.. When I enter "www.facebook.com " into the URL, my virus program (BitDefender) produces the following message on the monitor for me:

      Suspicious page blocked for your protection
      https://www.faccebook.com/

     Your connection to this web page is not safe due to an unmatching security certificate.

This means that the certificate was issued for a different web address than the one it is being used for, and you run the risk of exposing your data by accessing this page.

Since I updated a week ago I keep getting a warning of a bad site on sites that I know and trust. The problem is www.ui-deref.com Any ideas how to correct this?

As the title says, with both with https and http firefox displays this warning:

https://i.imgur.com/MQLsaCk.png

But no way to bypass it, trying to login to my ubiquiti edgerouter at http://192.168.1.1 or https://192.168.1.1

What can i do?

If I try to log into my router at 192.168.1.1 I get a message that says "Warning: Potential Security Risk Ahead". I expect that, but when I click on the Advanced button it doesn't do anything. Works fine with Chrome, so not my router or anti-virus. ???

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.
