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.

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.

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 The instructions I searched on the Internet are out of date.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

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.

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.

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.

Subject: Urgent Assistance Needed with Certificate Installation

Dear Team,

I hope this message finds you well. I am in urgent need of assistance regarding a Linux-based system where we have the Firefox browser installed. I need to establish a secure connection with one of my servers, which requires the installation of a certificate.

However, I am unable to locate the certificate export button in the certificate view or anywhere else in the browser. I have tried several methods without success.

Could you please help me with this issue as soon as possible? Your guidance would be greatly appreciated.

Thank you very much!

Best regards, Kishor

Hi : We are planning out server farm capacity, network gear needed, for a new site for our AI micro-services. We are curious when do you think that Firefox will support TLS 1.4 ? and will the overhead/utilization difference be between TLS 1.4 and 1.3 which we currently use exclusively. I understand that we are talking servers, and FireFox is a browser, but we cant dig up any real-world stats on the workload difference between the two. Any help would be appreciated.

Thank you for your time Albert Baker.
