When I tried to bring up crstrenght.pay.clickbank.net to pay for a medical product I got an Firefox error message. I have a feeling it was rigged to make you pay for a lot more bottles.

An error occurred during a connection to in.pinterest.com. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

I have a local Rocky Linux server running a nginx web server. I am using a Macos laptop. I am trying to install a self signed ssl certificate using openssl on my web server.. The certificate I generated works with Safari but not with Firefox. I have copied the certificate to both Safari and Firefox for local use. Privacy and Security, Manage Certificates, Your Certificates. Firefox complains that that my TLS is tls 1.1, when I am using tls 1.3:

An error occured during connection to tls-v1-1.badssl.com:1011. Peer using unsupported version of security protocol.

My test on my server shows:

sudo curl -v https://caprock.home

Furthermore I can't seem to delete the certificate from Firefox and re add it?

Whenever I try to connect to this sight I get PR_END_OF_FILE error. I am using windows 11. I have looked at numerous suggestions on how to resolve this without success. I am reluctant to create a new profile since I use Firefox on numerous computers.

To be honest. Firefox is starting to be a big pain to use. I'm starting to see more and more of this screen where it say's "Be careful. Something doesn't look right" Even when i go to the advance and say proceed. Nothing happens and i'm getting no where. I know many of the sites don't have anything to do with asking for credit card, Scam or even having popup's. I test the sites in other browsers and there work without any issues. But Firefox is starting to lock me out of many sites due to this. How can i make this stop. As i used Firefox for many years.

The sample that is in the screenshot is a Anime data base that i have also used for years. But today shows this. But was working fine yesteday. What is going on and how can i fix it. So i can start using the browser that i love on the sites i want to.

Just updated Firefox desktop (Win 10 with ESU) to 140.10.0ESR and now every site I try to access gives

Secure Connection Failed An error occurred during a connection to www.google.com. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR 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.

Sites were all working fine literally right before. No other changes at all. Have restarted a few times. Have disabled antivirus and adblocker extensions. Same problem including at google.com and even firefox. Note on the About Mozilla Firefox window says " Failed to check for updates". Also cannot even use the links there to go to What's new or Firefox help etc. (Gives Secure Connection Failed error). No proxy server. Have tried turning anti virus completely off. Just a combined modem/router -- basically vanilla.

Firefox is my primary browser so this is extremely disruptive. I am using Edge to access sites and post this.. though curiously enough I noticed it gave some error when checking for updates. Do not want to do anything there or will lose complete access.

Any suggestions .. or how to go back to a previous version, if necessary. Need a workable connection to file taxes next week so this is important. Thank you.

Moderator note: This question has been edited to correct the formatting.

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.

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 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

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.
