Why does Mozilla prevent me from accessing a website? | Firefox Support Forum

The server sends a 302 redirect:

When Firefox follows the redirect, the server sends a 302 redirect (from vHTTP to HTTPS):

When Firefox follows the redirect, the server realizes I haven't sent a necessary cookie and sends a 302 redirect to an age gate page:

Location: //www.elderscrollsonline.com/en-us/agegate

After I submit the age form, the site sends a 303 redirect to

Location: //www.elderscrollsonline.com/en-us

When Firefox follows the redirect, the server sends a 302 redirect to:

Location: http://www.elderscrollsonline.com/en-us/home

When Firefox follows the redirect, the server sends a 302 redirect (from HTTP to HTTPS):

Location: https://www.elderscrollsonline.com/en-us/home

So that seems to be the ultimate destination. You might want to bookmark that page.

If I start again after the site has set the age verification cookie:

I had no problem with the link you posted. Such errors are usually caused by a problem with the site certificate.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

Thank you. I tried updating Adobe Flash but had the same result.

Neither Internet Explorer nor Maxthon can access the site...

I have never had this issue previously with any other websites.

The internet is a very dangerous place for those who have no protection. We recommend using a firewall, anti-virus, and malware scanner programs.

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

The 'educated guesses' below are incorrect. I use Comodo Ice Dragon 60.0.2.10 & Windows 7, not Firefox 59.0 or Windows 10.

The Mozilla website, and most others, ask the browser for some information so that the web page can be properly displayed. (Type computer, type browser . . .)

I stopped using security about 10 years ago, no problems. I download 2 or 3 av & malware progs every few months for a scan, they bring up a few pups, that's all. I had many more problems when previously using security softwares.

I don't have Firefox installed, I don't use it.

Because this is the last sentence of the error page...

"Report errors like this to help Mozilla identify and block malicious sites."

At the start of the sentence is a tick box to turn this option on or off.

Interesting. You get a green lock; what is the address in the address bar at that point? I ask because there is quite a sequence of redirects with this site:

When my Firefox requests

The server sends a 302 redirect:

When Firefox follows the redirect, the server realizes I haven't sent a necessary cookie and sends a 302 redirect to an age gate page:

But I have taken your bookmark recommendation which works.

Thank you jscher2000.

Maybe it's because I am in Europe.
