I went into firefox security in preferences and deleted some of my certificates and now I can't log into or get on almost all of my old websites...is there a way to restore my original settings???? Thanks

How do you deal with this. Every time I open mail on Yahoo now after Win 10 and Monzilla updates this shows up. Secure Connection Failed

An error occurred during a connection to nearlyfooeyminus.com. SSL received a record that exceeded the maximum permissible length.

Error code: SSL_ERROR_RX_RECORD_TOO_LONG

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

Thanks

I can't open netflix or https://predatorhunteroutdoors.com . Why am I getting this message?

Secure Connection Failed

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.

I got a message that my certificate expired April 18,,,I dont know why? How do I get it restored. The message came on my desktop , FB is working fine and I can view my website flovalleynews,com on my phone....I dont understad this at all!

I am running windows 11. I routinely use firefox to access wireclub.com. Two days ago I started getting the following error:

We encountered a problem when completing your request.

We have been notified and are attempting to fix the problem as quickly as possible.

Invalid SSL certificate

The origin web server does not have a valid SSL certificate.

I tried clearing my cache that did not work. All other sites other than wireclub.com are working fine. I can access wireclub.com with Microsoft edge no problem. Any suggestions

Hello,

The website I log in for internet banking (https://www.sparkasse-rhein-maas.de/de/home.html) is shown as written in brackets when opened in Edge, but as www.sparkasse-rhein-maas.de/de/home.html when I open it in firefor. And Firefox tells me it's not safe when I want to log in. BUT - as I've only just discovered when I copied and pasted it in here - when copied it shows as https://www.sparkasse-rhein-maas.de/de/home.html, so safe after all? How can that be? I hope there's a good explanation.

Thanks in advance Bettina

I was browsing for vacant jobs in LinkedIn and ended up on this page: https://www.linkedin.com/jobs/view/4400116024/?trackingId=&refId=&midToken=AQHkKqfITpiwdw&midSig=2f8JsuceFtMYc1&trk=eml-email_jobs_application_rejected_01-similar_jobs-0-similar_job&trkEmail=eml-email_jobs_application_rejected_01-similar_jobs-0-similar_job-null-g3nlj~mo2hn6z8~of-null-null&eid=g3nlj-mo2hn6z8-of&otpToken=MTAwMjFlZTQxNjJhYzljM2JlMmYwMmVkNDAxYWU3YjA4NmNiZDQ0MzlkYWQ4NTZjNzljMTAxNjg0ZjU4NWZmM2YzZGZiN2JjNTVjNWZjZTc3YjhmZDg3ZWQ5YTExZWUyMDg1N2Q1YzI4OGNjNDU0MjU3YTEsMSwx But pressing the Apply button, did not take me to the application page, but instead a page that was saying: "Be careful. Something doesn’t look right. Firefox spotted a potentially serious security issue with jobs.tuvsud.com. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails." And there was no option to ignore this and just go to the site??? I needed to open MS Edge instead, to be able to apply for the job???

Whenever i try to connect to any site, it fails to load and displays the following error message:

This web site requires a secure connection. - The page you are trying to view cannot be shown because this web site requires a secure connection. - The issue is most likely with the web site, and there is nothing you can do to resolve it. - You can notify the web site’s administrator about the problem.

When i press 'advanced' it says: [Site name] 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.

This happens on every site i try to visit. I am on a samsung phone running android version 15. Other browsers do not have this problem (i am sending this from opera), and firefox works fine on my other devices.

Firefox browser has stopped opening websites on my Dell laptop. Get "secure connection failed" error message. Other browsers work just fine. I have refreshed, uninstalled and reinstalled Firefox from both firefox website (using Brave browser) and from MSN store.

i was using facebook until about 4 weeks ago. somehow it changed languages and while i was trying to put it back to english i was locked out.

this is part of the message i get

Firefox detected a potential security threat and did not continue to www.facebook.com because this website requires a secure connection.

keep getting message [ sometjing dosen't look right ] and certificate revoked for my bank login it lets me go to the website but wont let me log into it. this is for blue federal credit union bank so i have to use a different browser for it, it works fine on other browser like edge .but not Firefox please help with this issue i like Firefox would hate to have to switch browsers but if this doesn't get resolved then ill have no choice too thank you

I can't open my Wordpress website. I am using BlueHost portal. I get a message that says Something looks wrong and the following error code. SSL_ERROR_NO_CYPHER_OVERLAP

What do I do if Firefox wont let me log into my account on a website because the "certificate has been revoked"? I think it has to do with the "enhanced tracking protection" setting.

This is what the advanced message is:

Be careful. Something doesn’t look right.

Firefox spotted a potentially serious security issue with digital.bluefcu.com. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails. Advanced What makes the site look dangerous?

Firefox is warning you about this site because the certificate provided for digital.bluefcu.com has been revoked and isn’t trusted anymore.

Ever since I updated Firefox, my website has stopped loading properly. It works fine in Chrome and Edge, but in Firefox, I get a security warning page instead.

The message says:

Your connection is not secure

The website tried to negotiate an inadequate level of security. https://reminniapk.com/

uses security settings that might be outdated or not supported by Firefox, so the browser blocks it.

Error code: NS_ERROR_NET_INADEQUATE_SECURITY

I haven’t made any major changes recently, so I’m not sure why this started happening. Is this something that needs to be fixed on the server side, or is there any setting in Firefox that could be causing this?

Any help would be appreciated.

418 For years, I've been using a website that's crucial to my professional work. It's a national archive website. Today, I suddenly got an error about a missing certificate for this website, and there's no way to bypass it. The cause isn't the archives, but the latest Firefox update. Please fix this immediately or refund me for the days I'm off work—or maybe I'll lose my job because of you.

I am filing my taxes through Intuit. Something I have done for years with NO problem. I realize my system is old and something about the security certificate somewhere is not correct and cannot be changed. I am NOT a technician and all this security stuff is way above me. Normally a box pops up saying Advanced settings and another box that allows me to Trust the site and I am logged in. Now I want Intuit to download my CRA information and it cannot because of this certificate thing and there is no bypass. So now you want me to contact the web owner, whoever that is, the Government of Canada??? Good luck. and have a technical discussion that requires at least three degrees from MIT, which I do not have, to solve the issue???? This is bloody nuts and now I cannot file my taxes. I am about to go totally insane. This is way beyond the average individual's skill set.

Does anyone know how I can get around this??
