Why are you closing the baked-in cert expiration support thread two days before it happens? Wouldn't it make a whole ton more sense to leave it open during the actual problem period?

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 am getting the below message when trying to log into the EFTPS site. I have never had this issue before.

Did Not Connect: Potential Security Issue

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

What can you do about it?

www.eftps.gov 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.

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 read the The Times in the UK and have no problem viewing on my iPad and Google Pixel phone using the Firefox browser. However on my laptop using Firefox I get a screen that says Secure connection failed and recommends contacting the vendor as there is no workaround. On microsoft Edge there is no problem I like Firefox but for me this is a major limitation. Any ideas or suggestions welcome

Hi is many day i try to connect to chatgpt but return me this , (see attach foto ), is possible remove a check controll of certificate , is very useless and boring

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

Hello I have reinstalled my firefox on a new reinstall of windows 10 as my older version 10 crashed and went to the wall. however I have all my tabs and fafourites up and running but when i try and download my paid version of Nord VPN firefox comes back and says its not secure and wont load the website ? this has been working for me in the past. any advise would be greatfully accepted. thank you.

I cannot get past the secure connection failed! I have cleared cookies, cache, etc. I have turned off the firewall, and restarted my computer more times that I can count....

I am new to firefox customization. I need help to understand, how firefox picks up CA certificates from the global ca-certificates path in ubuntu and uses them in their own cert9.db

Currently, what I am trying is, If I have a rootCA certificate (which I generated using openssl), I want to keep it in a specific path, such that when firefox launches, it picks up that certificate and uses it. How can i achieve it.

I have tried using the policies.json, which works. But are there any other ways to achieve it?

Hi,

I saw some forums and even google is blocked and i have this problems. I paste here the problem but my browser is en french:

'Connexion bloquée : problème de sécurité potentiel

Firefox a détecté une menace potentielle de sécurité et a interrompu le chargement de pasarela.clave.gob.es, car ce site web nécessite une connexion sécurisée.

Que pouvez-vous faire ?

pasarela.clave.gob.es a recours à une stratégie de sécurité HTTP Strict Transport Security (HSTS), une connexion sécurisée est obligatoire pour y accéder. Vous ne pouvez pas ajouter d’exception pour visiter ce site.

Le problème vient probablement du site web, donc vous ne pouvez pas y remédier.

Si vous naviguez sur un réseau d’entreprise ou si vous utilisez un antivirus, vous pouvez contacter les équipes d’assistance pour obtenir de l’aide. Vous pouvez également signaler le problème aux personnes qui administrent le site web.'

Any ideas ? how is possible that this website is giving me error? is a government one. Is something wrong with the certificate ?

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

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?
