How to Fix Secure Connection Failed in Firefox? (3 Ways)


While using Mozilla Firefox, you may encounter an error message that says “Secure Connection Failed,” preventing you from accessing the intended web page. This might be aggravating, especially if you are looking for vital work. The error might occur as a result of either malfunctioning software or wrong browser settings.


While the error is annoying, there are a handful of workarounds that can address the issue and allow you to continue browsing your favourite websites on Firefox. Let’s see what we can do to solve the problem.



Method 1: Disable SSL scanning in your antivirus software.

This solution is intended for those who use security or antivirus software (for instance, McAfee or Norton). These security solutions have an inbuilt SSL scanning capability that, when activated, attempts to filter out the web page (you want to view it), guaranteeing that you browse over a secure network connection. This is when the error notice appears. So, how do you disable this option? Let’s see what happens.


Step 1: Navigate to your antivirus software’s Settings area and check for the SSL scanning or SSL filtering feature. Once you’ve found it, simply uncheck/deactivate it.


Now, open the same web page in your Firefox browser, and the error should be gone. If it still does, use the second technique.


Method 2: Modify the SSL Settings in Firefox


Step 1: Open the Firefox browser, type the below address in the address bar, and hit Enter:



To view the list of preferences, click Show All.


About Config Show All Firefox Address Bar


Step 2: In the search box, put security.ssl.enable_ocsp_stapling. Then, double-click on the result to set the value field to false.


That’s all. You should now be able to easily and error-free access your preferred web pages.


Method 3: Enable TLS versions 1.0 and 1.1.


The minimum TLS version supported by Firefox in newer versions is 1.2. If you receive an error and see a button on that page that says Enable TLS 1.0 and 1.1, simply click on that button and continue.
