    The site goes down frequently. sometimes it doesn’t work in either Chrome or Safari but it works fine with Firefox and sometimes it doesn’t work with either.

    Install the Really Simple application and the bad situation has arisen, the php version is updated and the site has the most fake problems.

    Correctly:

    In Chrome gets this message: ERR_QUIC_PROTOCOL_ERROR

    In Firefox I got this message: SSL_ERROR_INTERNAL_ERROR_ALERT

    The page I need help with: [log in to see the link]

    @dancaprilesm It worked for me, but it could be because this image is not secure. You may need to reload it to make it secure or edit the file path to include https

    Also, try clearing the entire browser cache

    OKAY. Thanks. After I was able to access the web page, I deleted this image and all the others that I don’t use. I also cleared my browser cache and the site came down.

    @dancaprilesm Después de verificar nuevamente, falló, pero parece que SSL estaba tratando de conectarse desde dos servidores diferentes. Es posible que 50.31.174.38 y 148.105.251.18 (que fallaron) deban verificar la ubicación del certificado nuevamente o volver a emitirlo.

Disabling Firefox’s ‘Secure Connection Failed’ Warning

Posted onOctober 21, 2008 by Anil Polat

site InternetAunque controvertida , la advertencia de error de conexión segura de Firefox 3, que se muestra cuando el certificado digital de un sitio web no es válido o está autofirmado, se puede desactivar fácilmente.

  1. En la barra de direcciones, escriba about:config > haga clic en ‘Enter’.
  2. Recibirá un mensaje de advertencia, ¡Esto podría anular su garantía! Haga clic en ¡ Tendré cuidado, lo prometo!
  3. Haga doble clic en browser.ssl_override_behavior y cambie el valor de ‘1’ a ‘2’.
  4. Reinicie Firefox.

Instead of disabling the prompt completely, you can display a warning, without having to add an exception.

  • browser.xul.error_pages.expert_bad_cert = true

Firefox’s antiphishing warnings will continue to warn users if a specific site is suspicious. I’m not convinced that the secure connection failure warning really helps the average user, as they won’t know what it is. Either way, now you can avoid it.

How to fix PR_END_OF_FILE_ERROR: 3 methods that work How to Fix PR_END_OF_FILE_ERROR: 3 Methods That Work

Most websites implement a secure connection protocol using Secure Sockets Layers (SSL) or Transport Layer Security (TLS). While this secure connection creates a safe browsing experience, it can also trigger some errors that may frustrate users.

One of such messages is PR_END_OF_FILE_ERROR – Firefox browser may throw this error from time to time. This article will explain what it is, its causes, and three simple ways to fix the PR_END_OF_FILE_ERROR secure connection failed error.

What Causes the PR_END_OF_FILE_ERROR (Secure Connection Failed) Error?

Error message PR_END_OF_FILE_ERROR PR_END_OF_FILE_ERROR error message

The PR_END_OF_FILE_ERROR error message appears when the Mozilla Firefox browser can’t establish a secure connection. It is a Firefox-specific error and won’t appear in any other browser. Thus, this often affects many websites you try to visit, as the problem is on the client-side.

To understand why PR_END_OF_FILE_ERROR happens, we have to understand the process of establishing a secure connection between a browser and a website.

Your browser has a cipher suite – a set of algorithms that makes a secure connection over an encrypted protocol possible. When you visit a website that uses SSL or TLS, the browser runs through the cipher suite until it finds a matching algorithm for the connection.

However, if Firefox reaches the end of the cipher suite file and doesn’t find a match, it results in the PR_END_OF_FILE_ERROR message.

In general, this error has four possible causes:

  • Virtual Private Network (VPN) or proxy server interference. A VPN and a proxy server act as a middle man between your computer and website server, hiding your IP address and location. If not configured correctly, VPN and proxy services can trigger PR_END_OF_FILE_ERROR.
  • Incorrect cipher variants. It may happen when you’ve modified SSL settings on your computer or browser. In this case, the browser enforces a cipher version that’s not supported either by Firefox or the website.
  • Corrupted Firefox profile. Synchronization issues between desktop and mobile browsers can corrupt a Firefox profile, triggering the Firefox secure connection failed error.
  • Third-party security software. Antivirus software can sometimes misidentify safe websites and block your access to them.

3 Ways to Fix PR_END_OF_FILE_ERROR

Multiple aspects can trigger the PR_END_OF_FILE_ERROR secure connection failed issue. We will cover three ways to fix it from different possible sources of the error – the Firefox settings, a proxy or VPN connection, and third-party security software.

Before proceeding to the different methods to fix the secure connection failed error, check if the website is down for all visitors or whether you’re the only one unable to access it.

1. Go Through Your Firefox Settings

Since PR_END_OF_FILE_ERROR is a Firefox-specific issue, we’ll start by reviewing the browser settings.

Reset Firefox SSL Settings

You may have modified the browser’s SSL settings, triggering the issue. Refreshing Firefox settings can resolve this secure connection error. Follow these steps to do so:

  1. Click the hamburger menu at the top-right corner and click Help.

firefox help menu Firefox help menu

  1. Select More Troubleshooting Information.

Learn more about troubleshooting Firefox More troubleshooting information on Firefox

  1. The Troubleshooting Information tab will show the diagnostics. At the top-right corner, click the Refresh Firefox button under Give Firefox a tune up.

Button to refresh Firefox Button to refresh Firefox

  1. A prompt pop-up screen will appear. Click the Refresh Firefox button.

Confirmation message to update Firefox. Confirmation prompt to refresh Firefox.

The browser will automatically close, and a new window will appear, showing the reset progress. Once it restarts, the browser will use its default configuration, including the SSL settings.

Revisit the website to see whether the reset resolved the issue. If the error persists, try the next method.

Disable DNS Over HTTPS

When you try to open a website, your browser sends a DNS request to the server. DNS over HTTPS is a protocol that sends these requests through HTTPS.

Enabling it prevents malicious attackers from eavesdropping and seeing your online activity. Unfortunately, this feature can also trigger the PR_END_OF_FILE_ERROR.

However, disabling it is a quick fix. Follow these steps to disable DNS over HTTPS:

  1. Click on the hamburger menu at the top-right corner and click Settings.

Configuración de firefox Firefox settings

  1. On the General screen, scroll down to the bottom, and you’ll find the Network Settings section. Click Settings.

Configuración de red en Firefox Network settings on Firefox

  1. At the bottom of the Connection Settings window, there’s an Enable DNS over HTTPS option. Uncheck the box and click OK.

Configuración de DNS sobre HTTPS en Firefox DNS over HTTPS setting on Firefox

Restart the browser and see if this resolved the secure connection failed error.

Create a New Firefox Profile

If all the previous methods for PR_END_OF_FILE Firefox error didn’t work, your Firefox profile might be corrupted. So, you will need to create a new profile.

We suggest exporting bookmarks before creating a new profile. Therefore, if this method resolves the error, you can easily import the bookmarks to use on your new Firefox browser profile.

  1. Open the bookmark manager by clicking CTRL+Shift+O. Alternatively, click the hamburger menu, select Bookmarks, and click Manage bookmarks at the bottom.
  2. Select All Bookmarks.

Administrador de marcadores de Firefox Firefox bookmarks manager

  1. Click Import and Backup and select Export Bookmarks to HTML.

Exportar marcadores en Firefox Export bookmarks on Firefox

  1. A new window will appear. Select the folder to save the bookmark data and click Save.

Now, follow these steps to create a new profile.

  1. Type about:profiles in the address bar and press Enter.
  2. Click the Create a New Profile button.

Crear un nuevo perfil en Firefox Create a new profile on Firefox

  1. The Create Profile Wizard will appear. Follow the on-screen instructions.

Crear asistente de perfil en Firefox Create profile wizard on Firefox

  1. Once it’s done, the new profile will appear on the profile manager page.
  2. Click Launch profile in new browser.

Lanzar un nuevo perfil en Firefox Lancer un nouveau profil sur Firefox

Try to revisit the website with the new profile. If it works, then the corrupt Firefox profile was the main issue causing secure connection failed error.

Now all you have to do is import the bookmarks to the new profile. Similar to the export bookmark process, open the bookmark manager and choose Import Bookmarks from HTML, then select the saved file.

2. Turn Off Your VPN or Proxy

Browsing the internet using a proxy or VPN server can also trigger the PR_END_OF_FILE_ERROR. These services interfere with the connection by acting like a middle man, which sometimes makes the connection protocol unable to find the correct cipher suites.

If that’s the case, disabling VPN or proxy should fix the PR_END_OF_FILE_ERROR.

The steps to turn it off depend on the VPN application you use but, most of the time, it’s a simple process. Below is an example of the NordLayer VPN app’s interface:

Bouton d'apagado de VPN Bouton de désactivation du VPN

If you use a proxy connection, you have to disable it from the system’s proxy settings, and the steps are different for Windows and macOS users.

Windows

Turn off the proxy server in the system settings. Here are the steps to do so:

  1. Open the Windows Settings and go to Network and Internet.

Configuration de red e Internet en Windows Paramètres réseau et Internet sous Windows

  1. Select Proxy on the left panel.
  2. Scroll down to the Manual proxy setup section and switch off Use a proxy server.

Configuration du serveur proxy sous Windows Configuration du serveur proxy sous Windows

  1. Reboot the computer so that the change takes place and revisit the website using the Firefox browser.

macOS

In macOS, you have to uncheck all proxy protocols, like so:

  1. Open System Preferences and select Network.

Configuration de red et des préférences du système MacOS Paramètres réseau dans les préférences système MacOS

  1. Select Wi-Fi on the left panel, then click the Advanced button.

Advanced configuration of Wi-Fi and MacOS Advanced Wi-Fi Settings on MacOS

  1. Open the Proxies tab. Uncheck all items on the Select a protocol to configure box and click OK.

Proxy Protocols and MacOS Proxy protocols on macOS

  1. Reboot your computer and use the Firefox browser to revisit the website.

Firefox Proxy Settings

It’s also possible that the proxy connection is active on your Firefox connection settings, causing PR_END_OF_FILE_ERROR. Follow these steps to turn it off:

  1. Haga clic en el menú de hamburguesas en la esquina superior derecha y seleccione Configuración .
  2. Desplácese hacia abajo hasta encontrar la sección Configuración de red y haga clic en Configuración .

Configuring Red in Firefox Network settings on Firefox

  1. Aparecerá la ventana Configuración de conexión ; encontrará Configurar acceso de proxy a Internet en la parte superior. Marque la opción Sin proxy y haga clic en Aceptar para guardar.

Configuring proxy in Firefox, removing "Sin proxy" option Proxy settings on Firefox, highlighting the "No proxy" option

Ahora, reinicia Firefox para ver si funcionó.

3. Deshabilitar temporalmente el software de seguridad

Este método es más aplicable a los usuarios de Windows, ya que el sistema operativo a menudo se basa en software de seguridad de terceros.

Algunos software de seguridad o antivirus como Kaspersky , BitDefender y ESET pueden percibir los conjuntos de cifrado como amenazas potenciales. En ese caso, interceptan la conexión y usan su protocolo seguro, lo que resulta en un error de falla de conexión segura de Firefox.

Puede considerar apagar el software por completo, pero hacerlo expondrá su computadora a riesgos de seguridad.

Recomendamos deshabilitar solo la protección en tiempo real en su software antivirus, si es posible. Esta característica rastrea su actividad e intercepta la conexión de red inmediatamente si encuentra alguna amenaza.

If you can’t download manually, the only option is disabled for full software. The method is different depending on the software used. In general, you can find the adjustments in the control panel or in the configuration section.

Endpoint security interface Endpoint Security Interface

After disabling the software, reboot the computer and intend to return to the website. If the security software is real, this is the root cause of the problem, which has been replaced by a single active PR_END_OF_FILE_ERROR.

Conclusion

The Mozilla Firefox segura connection error occurs when you browse without being able to encounter a coincident cifrado conjunto para establish a segura connection con el website.

This can trigger misconfiguration in browser configuration, VPN or proxy issues, or interference with security software.

In short, this is what you can do to fix this Firefox error:

  1. I went through the Firefox configuration . The simplest form of solution is connection error segura is restoring the configuration of Firefox. If not functional, disable DNS over HTTPS or create a new Firefox profile.
  2. Disable VPN client or proxy service . Su VPN and its proxy service may interfere with the connection. Intente apagarlos para resolver el error.
  3. Deactivate the security software . Some security programs may consider cipher suites to be security threats. Disable real-time protection in the software if possible. Contrariwise, the software is temporarily inapt and, if you find the secure connection error, look for an alternative software.
