Are you having trouble with Error Code SSL_ERROR_UNSUPPORTED_VERSION on Firefox or Brave Browser? Have no fear! This article will help you out!
Firefox and Brave web browsers are some of the widely used browsers online. However, there are instances when problems on your browsers may occur.
Ways to Resolve Firefox or Brave Browser Error Code SSL_Error_Unsupported_Version
If you encounter the SSL_ERROR_UNSUPPORTED_VERSION error on your Firefox or Brave browser, you can troubleshoot it by following the solutions below.
Diagnose the SSL_Error_Unsupported_Version Error on your Browser
Depending on your operating system, this could require downloading an updated version of Firefox from the Mozilla website or updating it through the Settings menu of Brave Browser.
- If possible, try connecting to the same server again with another web browser such as Chrome or Safari.
- If the connection works on another browser but not Firefox/Brave, then you should contact your website administrator for more help since they must have configured their server incorrectly.
- Otherwise, make sure that any security plugins installed in Firefox/Brave are up-to-date and properly configured.
- Finally, check if you’re connected to a Virtual Private Network (VPN) or Proxy Server when attempting to connect to a particular site because these connections can interfere with TLS protocol compatibility between servers and browsers.
- It’s also recommended that you disable all third-party extensions before trying to access certain sites as some extensions may cause conflicts which would prevent successful loading of content over HTTPS connections.
TIP: Always double check your browser settings and software updates when diagnosing SSL errors like SSL_error_unsupported_version!
Enable TLS in Firefox/Brave Browser
This can be done with a few simple steps:
- First of all, open the Firefox/Brave browser and navigate to Options > General > Network Proxy> Settings.
- Here you will find several options related to TLS protocol settings.
- Next, select the option that says Enable TLS 1.0, 1.1 and 1.2 protocols for secure connections (recommended) and click OK.
- You may also want to check if other security-related options such as SSL v3 are enabled or not in this window.
It is recommended to use the latest version of TLS available for your device since older versions may contain vulnerabilities or bugs that could leave you exposed online.
To guarantee greatest security against digital dangers, ensure that both server side and client-side frameworks are fully informed regarding the most recent form of TLS:
Server-Side Systems TLS Security Methods
- Ensure that the web servers have been configured properly so they support only strong cryptography ciphers like AES256+SHA2 etc., which offer better encryption standards than previous versions of TLS protocol used by browsers.
- Check if there is any software installed on the server that might prevent newer versions of TLS from being used while communicating between clients and web servers over HTTPS connection.
Client-Side Systems TLS Security Methods
- Make sure that firewall rules are set correctly on client computers so they allow traffic through port 443 (which is used by default for HTTPS communication).
- Test different browsers to see what works best when connecting to a website using an outdated version of TLS – some browsers may work better than others due to compatibility issues between them and old versions of TLS protocol.
Clear SSL State in Firefox/Brave Browser
- To do this, you must open the settings page of your chosen browser and go to Privacy & Security.
- From there, select View certificates from the options available.
- This will bring up a window showing all installed certificates on your system; you should then select Clear SSL State.
- Once the Clear SSL State button has been clicked, it will prompt you to confirm the action. After confirming that you want to clear the SSL state, any existing stored certificate information should be removed from your browser.
- If successful, restarting your browser should resolve any issues with error code SSL_error_unsupported_version when accessing secure websites.
However, if this does not work then further investigation may need to take place into other potential causes for this issue. Hope this helps!
