You can consider the following approaches to resolve common SSL errors on the Firefox web browser.
You must ensure that your Firefox browser is updated with the latest version. Updating the browser is the first step that every troubleshooting guy performs to resolve common SSL errors on Firefox.
To update the Firefox browser, follow the below steps:
Step 1: Open the browser menu by clicking on the three-bar icon on the right. Then, Help >> About Firefox.
Step 2: If there is any update, Firefox will automatically download and install it.
Step 3: Once the update is complete, restart the browser and try to open the website.
In addition, you can also uninstall the outdated version and install the latest browser version from the official Firefox website.
Clearing cache and browser history is one of the methods for resolving the “SSL_ERROR_RX_RECORD_TOO_LONG” error. To do so, you should open your Firefox browser and follow the below procedure:
Step 1: Use the three-bar icon to open the menu.
Step 2: From the menu, choose Settings >> Privacy & Security tab.
Step 3: Click on “Clear Data” available in the “Cookie and Site Data” section.
Step 4: A new dialog will appear. Select the “Cookies and Site Data” and “Cache Web Content” checkboxes.
Step 5: Click on Clear.
Once you clear the site data and cookies, scroll down to the “History” section. Similarly, you should clear the history as well.
The wrong proxy settings are another reason to see Firefox SSL errors. To fix the SSL error, you can follow the procedure as mentioned:
Step 1: Open the browser manager and choose “Settings”.
Step 2: Go to “Network Settings” and choose Settings present at the bottom.
Step 3: Choose the “No Proxy” option and click on “OK”.
Step 4: Restart the browser to confirm whether the SSL issue is resolved.
There are some websites that establish communication channels only after undergoing specific encryption protocols. However, if the site doesn’t find a compatible protocol, it displays the “SSL_ERROR_NO_CYPHER_OVERLAP” error.
To resolve such issues, you can perform the following process:
Step 1: Open a new Firefox tab, and in the address bar, input “about:config“.
Step 2: Once you hit enter, a message will be displayed as below. You should click on “Accept the Risk and Continue“.
Step 3: In the search field, input “tls“
Step 4: You will see values matching with input in bold. Now, right-click on those values and choose “Reset“
Step 5: Perform a similar procedure for “ssl3“.
Step 6: Set the values for “security.ssl3.dhe_rsa_aes_128_sha” and “security.ssl3.dhe_rsa_aes_256_sha” to false.
It’s not recommended to bypass the browser configurations. But, in case you need to visit a specific website for some urgent task, it can help.
The steps for bypassing browser configuration are as follows:
Step 1: Open the browser settings.
Step 2: Navigate to “Privacy and Security”.
Step 3: Scroll to the “Security” section and uncheck the “Block dangerous and deceptive content“
As a result, the issue will be fixed. However, if you still face an error, there can be a possibility of server-side misconfiguration, or the site should be using the unsupported RC4 cipher.
Besides removing errors, adding a certificate to the browser helps verify authenticity efficiently and saves time in establishing a connection with the server.
The steps to manually add a certificate are as follows:
Step 1: Go to Firefox browser settings from the three-bar icon.
Step 2: Use the search field to find settings associated with Certificates.
Step 3: Open the Certificate Manager using the “View Certificates” option.
Step 4: Under “Your Certificates” go to “Import“
Step 5: Choose the CA-issued certificate from the system memory and click OK.
Now, the certificate will be imported to the browser, and errors will be removed while visiting that particular website associated with the certificate.
To disable SSL warnings in the Firefox browser, you can execute the following process. But you should know that SSL and security experts don’t recommend this method. So, you should execute it after thorough decision-making.
Step 1: In the new tab, input “about:config” in the address bar and use Enter key.
Step 2: Accept the risk and continue.
Step 3: In the search field, input “browser.ssl_override_behavior”.
Step 4: Change the value of searched input from 2 to 1. As a result, your Firefox browser will not display warnings and errors.
This approach is for businesses operating websites and providing online services to their customers. They all should use an authentic SSL certificate from a reliable certificate authority, such as Comodo, Sectigo, Certera, and more.
In addition, you should purchase an SSL certificate from a trusted CA-registered partner. It will help you align with the latest CA/B standards, remove errors, and provide a buttery smooth experience to end-users.
