Warning: Potential Security Risk Ahead

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

What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to nrega.nic.in because this website requires a secure connection.

What can you do about it?

nrega.nic.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.

Probably nothing, since it’s likely there’s a problem with the site itself.

I'm getting a PR_CONNECT_RESET_ERROR on my PC when trying to web browse. Same problem with other browsers. Was working fine till a few days ago The URL box has 'Not Secure' before each URL address I try. Have looked up solutions on YT to no avail eg clearing cache etc

My Laptop has no problem with this.

Hi, Since three or four months, whenever I log into Outlook live, either on Mac or Windows PC, I get a security warning saying that the information will not be secure (Please see attachment.) When I log into the same account, from Edge for example, I do not get the warning popup. I really enjoy using Firefox and would love to continue but this case is worrying me a bit. Any idea to help? Thank you very much, Mathieu B.

Secure Connection Failed Error Code SSL_ERROR_RX_RECORD_TOO_LONG displayed when connected to Cow.huntforeeenst.com SSL Unable to notify website Error code is displayed when connected to Yahoo Mail.

I used to be able to connect with Firefox (with a warning message from you) to my local Netgear NAS, but now it just says:

Secure Connection Failed An error occurred during a connection to 192.168.1.100. Peer using unsupported version of security protocol. Error code: SSL_ERROR_UNSUPPORTED_VERSION The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the web site owners to inform them of this problem. This web site might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox.

How can I still override this with Firefox. It's really important I can connect to my NAS.

With thanks,

Nick Curley

I don't understand your philosophy of preventing someone from danger. If I am trying to log into my local router and your product says "no, its not secure" I am faced with at least two problems: First I am denied access to my equipment; and secondly, I am prevented from having control of my own decision-making as poor as it might be. It is especially annoying that your explanations are empty and vacuous, jargon-filled and full of misdirection, sending me into a world of data, not information, with the prospect of spending too much time on things I don't want to know. That seems more Microsoft than Mozilla. That is Mozilla as a consumer product, not Mozilla as an IT technologist.

Why can't you simply say we think its safer for you for us to block your request, but if you insist, do this. But beware, these are the possible consequences.

I try to connect to a web site but I get this response:

Firefox is giving me an error on https://stemgateway.nasa.gov but the site is perfectly accessible using MS Edge and using Firefox on another computer. I uninstalled and reinstalled Firefox, changed the proxy settings to not use a proxy, tested a VPN, and changed DNS servers. Below is a picture of the error and of the certificate which seems to be present in Firefox already.

I'm trying to access a local web application (GoPhish) running at https://127.0.0.1:3333 on Kali Linux. Firefox is showing a security warning and won't let me access the site . How can l bypass this warning safely, or add an exception for local addresses with self-singned certificates?

An error occurred during a connection to portal.esic.gov.in. SSL received a record that exceeded the maximum permissible length.

I'm using firefox in my company's intranet, it needn't to check whether the website is secure or not. So this warning is so annoying.

I want to turn it off, but how? The instructions I searched on the Internet are out of date.

The browser version is 137.0
