What is SSL ERROR DOWNGRADE WITH EARLY DATA on Firefox Browser?

SSL_ERROR_DOWNGRADE_WITH_EARLY_DATA is a fancy term for a hiccup in the security handshake between your Firefox browser and a website. In simpler terms, when you try to access a secure website, there’s a protocol that ensures your connection is safe and encrypted. The error occurs when this process encounters an unexpected obstacle.

Why Does This Firefox Web Browser SSL Security Issue Happen?

This error usually happens when there’s an attempt to “downgrade” the secure connection to an older, less secure version. Browsers prefer the latest and greatest security protocols to keep your data safe. When this downgrade attempt is detected, Firefox raises the SSL_ERROR_DOWNGRADE_WITH_EARLY_DATA flag to warn you that something fishy might be going on.

How to Troubleshoot and Fix Firefox Error Code SSL_ERROR_DOWNGRADE_WITH_EARLY_DATA

Now, let’s get to the solution. Follow these simple steps to get rid of the SSL ERROR DOWNGRADE WITH EARLY DATA error code:

Ensure you are using the latest version of Firefox. Developers regularly release updates to fix bugs and enhance security.

  • To update, click on the three horizontal lines in the top-right corner.
  • Go to “Help,” and then select “About Firefox.”
  • If an update is available, Firefox will automatically download and install it.

Method #2 – Check Your Internet Connection

Sometimes, a shaky internet connection can trigger SSL errors. Make sure you have a stable and secure internet connection. If you’re on a public Wi-Fi network, try switching to a more reliable connection.

Method #3 – Clear Firefox Browser Cache and Cookies

Cached data and cookies can sometimes interfere with secure connections.

  • Go to the menu.
  • Select “History,” and then choose “Clear Recent History.”
  • Make sure to select “Everything” in the “Time Range to Clear” dropdown.
  • Check both “Cookies” and “Cache” before clicking “Clear Now.”

Method #4 – Disable Security Software Temporarily

Firewall or antivirus software might be too cautious and could block secure connections. Temporarily disable your security software and see if the problem persists. Remember to enable it again once you’ve tested the connection.

Method #5 – Enable TLS 1.3

TLS (Transport Layer Security) is the protocol responsible for secure communication on the Internet. Enabling TLS 1.3 might help resolve the SSL_ERROR_DOWNGRADE_WITH_EARLY_DATA issue. Type “about:config” in the Firefox address bar, search for “security.tls.version.max,” and set it to 4.

Method #6 – Try Using Another Browser

Remember to keep your browser updated, check your internet connection, and clear cache and cookies regularly. By following these steps, you’ll be back to browsing securely in no time.
