A Secure Socket Layer, or SSL, is the standard security technology to establish a secure connection between two systems. It safeguards any sensitive data that is being transmitted from your web browsers to the webserver or vice versa. With this security technology, all your potential personal and financial information will be encrypted and invisible from criminals’ eyes during transmission.
Transport Layer Security, or TLS, is an updated version of SSL, which is more secure. Nowadays, the first generation and outdated SSL version is no longer used. I still refer to security certificates as SSL certificates because it’s the most commonly used term. Not only me, but the majority of people are also now using the SSL term instead of the TLS term. When you purchase an SSL certificate from NameCheap.com or Godaddy.com, you actually purchase the most up to date TLS certificates.
Note: The “two systems” concept can be a client and a server, for example, a web browser and an online shopping store. This can be a server to a server, for example, a web-based application (that’s stored in a server A) connects to a server B via the SSL method.
Why Does Your Web Browser Show An Invalid SSL Certificate Warning?
When you browse a website through the HTTPS protocol, its SSL certificate is always verified by your web browser and then starts to establish a secure connection if it is valid.
However, if the web browser can’t validate the SSL certificate, it will warn you about an unsafe website with different error messages, depending on which web browser you are using. For example, if you use the Google Chrome browser, you will get this error message: Your Connection Is Not Private. Similarly, Mozilla Firefox browser will show “Your Connection Is Not Secure,” and Microsoft Edge will display “This site is not secure” as the error message.
How To Disable Invalid SSL Certificate Warning On Your Web Browser
Each web browser has a different SSL error message and has a different way to turn off this type of warning. Thus, you need to choose the right method to disable it.
But note that turning off the SSL alert is not a good thing unless you are doing something that you know very well. The reason is that when you turn it off, you will no longer receive the dangerous alert when visiting an insecure website. And instead of blocking you at the error screen, your web browser will let you go straight to an unsafe website – and sometimes, that website contains a malicious program that can affect your computer.
So be careful when turning off this feature on your web browser.
How To Disable Invalid SSL Certificate Warning In Google Chrome
To disable the invalid SSL warning function in Google Chrome, copy chrome://flags, paste into the address bar, and then press Enter. You can also type it by hand.
In the next screen, search for #allow-insecure-localhost. The “Allow invalid certificates for resources loaded from localhost” option will show up. All you need to do is to turn this option on and restart your Google Chrome browser.
From now on, your browser won’t show any alert when it finds an invalid SSL certificate. Instead, it will let you go directly to the HTTPS website with an error certificate.
How To Disable Invalid SSL Certificate Warning In Mozilla Firefox
If you want to visit a website with an invalid SSL certificate but don’t want your Firefox browser to stop you or display any warning message, then just follow these steps.
Firstly, go to Mozilla Firefox’s advanced configuration preferences by copying about:config, paste into the address bar and then press Enter.
In the next step, click on Accept the Risk and Continue button when you see this message: “Changing advanced configuration preferences can impact Firefox performance or security.”
Next, find browser.ssl_override_behavior and change its value from 2 to 1.
Your Mozilla Firefox browser is no longer warning or blocking you from accessing any websites that have invalid SSL certificates.
How To Disable Invalid SSL Certificate Warning In Edge, Opera, And Safari
Unfortunately, there is no effective method to turn off the invalid SSL certificate warning in Microsoft Edge, Opera, or Safari browser, at this moment. I have tried a few suggested solutions to disable this irritating alert in Microsoft Edge, but they don’t work. Besides, Opera and Safari don’t give us any place to turn it off. It seems Opera Software and Apple don’t allow us to adjust this feature due to security purposes.
If they allow us to change it, I will let you know.
I know that when you see these types of errors in your web browser, you might feel very uncomfortable. However, these unpleasant things are protecting you from online threats. If you remove this layer of protection, your computer is at risk of being compromised by various types of malware. And what’s more, attackers can steal your personal information, bank accounts, and all other sensitive data on your computer.
Therefore, I would recommend you consider carefully when you turn this feature off. It might be useful for you right away, but in the long run, it’s no good. Of course, there are exceptions; for example, if you are testing your own website.
