I am trying to connect to a web page but keep getting the following message:-

An error occurred during a connection to WWW.castlewater.co.uk. Peer's certificate has been revoked.

I CAN connect via the Edge browser?

Do I need to change a setting?

Regards

I have a router set up at a remote site with a device that has a built in web server that allows viewing the items displayed. The router quit working so i replaced it with another one with the same configuration but now when I try to access through it The browser is complaining that it is unsecure and apparently resets the connection. I don't care if it is unsecure it is my site/router and I want to connect. I have used this configuration many times with no problems but firefox has done something to prevent it from working anymore, this started being a problem with some of these setups a couple years ago. How do I get it to connect anyway.

I have been using my email for years and suddenly today this message came up and I cannot access my email because an error message came up. i accessed earlier today and then this message. I use my provider as my home page and it has never been an issue before. The only thing I have changed is I downloaded a codec update. I can still receive emails from this address on my phone. I can still access all the sites I visit except my webmail.This is the full message: An error occurred during a connection to webmail.westnet.com.au. Peer’s Certificate has been revoked.

Error code: SEC_ERROR_REVOKED_CERTIFICATE

I am trying to backup a certificate using certificate manager but I keep getting the error “Failed to create PKCS #12 backup file for unknown reasons” I have tried everything to get this to work

I have been using the G-MAIL account for a very long time. I have never experienced problems while using it. I have also on a previous occasion registered here at Firefox and used it successfully, the same g-mail account for my emails. I have just registered and I am now blocked from accessing my emails because of a false certificate. When I registered previously here on Firefox I was able to use the same g-mail account. When did its certificate become faulty?' How do I access my emails? Does this mean I have to start new email addresses acceptable here at Firefox or its a go back to where you came from or try somewhere else?

My bank says it is your problem. This website will open using Google but not Firefox. I am wondering if somewhere in your last "update" there was a change which clashes with my bank's security settings (or whatever). When I try to open the website (Chase.com), the screen shows a solid blue screen and a twirling circle which usually precedes the opening to my account page. It twirls FOREVER! It never opens! It makes no sense to me whatever. HELP!!

I have recently received a notice from Mozilla informing me that the Security Certificate for Firefox is set to expire, and if I do not update it, Firefox may develop issues and stop functioning. As I am not very tech savy, and do not understand the language, I do not know igf/how this will affect my system. It is set to update automatically. I have included a screenshot of the notice below. I keep the system simple, and do not use add-ons, etc. Can someone please explain what all this means in laymans terms?

One morning could not connect to email/ATT. This is the error message I got: Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over. ATT came to home to look into hookup, etc. Could not fix. They advised Firefox could be corrupted. Should I reinstall Firefox. Had to go thru Chrome for email. Have Windows 11. Thank you.

Please help me purchase a NM Gift Certificate for my daughter Caroline Campbell. She has an account with you but I do not and I'm overwhelmed by the process. Lisa Nichol [edited email from community support forum]

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'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 have written so many times about this issue.

Just stop sending useless warnings about Australian Government Websites. The BOM (Bureau of Meteorology) provides weather information on request. It is a free service and does not require a subscription.

So I'm trying to access Greenfly but I'm getting this error message: SEC_ERROR_REVOKED_CERTIFICATE.

Please see attached image as all checks are good for the credentials. I've tried erasing cookies but no luck.

Any other options?
