How to Clear HSTS Settings in Chrome and Firefox Browsers

How to Clear HSTS Settings in Chrome and Firefox Browsers

Here is a step by step guide to clearing the HSTS settings in your favorite browser.

First off, let us commence with the basics. What is HSTS? It is an acronym for HTTP Strict Transport Security. It enables browsers to get better connections through HTTPS while restricting HTTP connections that are the gateway to most brute attacks by hackers. HTTP websites are being phased out of the scene and swiftly being replaced by HTTPS which is more secure because it uses SSL certificates that are really the backbone of all secure and safe sites.

HSTS is slowly gaining traction by many developers and clients on the web. However, rolling out the entire HSTS protocol on your browser can hamper some errors in your browser in several cases. That is why you need to clear these errors so you can continue enjoying the HSTS settings on your browser. It goes without mentioning that HSTS will aid the SSL certificate in preventing interruption by hackers and even leaking of sensitive information you may be sharing over the web.

This protocol was created to curb a rise in SSL Strip attacks. Hackers had devised a way of downgrading HTTPS connections to HTTP.  This caused more websites to get hacked and that is where the HSTS was invented, it works by transmitting a policy to a web page’s header and thus forcing it to create a secure HTTPS connection upon a person paying a visit to the website
