Brief background why everyone is after TLS

As per Payment Card Industry (PCI) Data Security Standard (DSS), for securing payment data, all data processor needs to stop using old SSL protocols and early version of TLS. The deadline was 30th June 2018.
So SSL 2.0, SSL 3.0 and TLS 1.0 has be to discontinued after the deadline and recommended to use TLS 1.1 or higher (TLS 1.2 is highly recommended) for implementing a more secure encryption protocol.

So most of the website owners are now disabling SSL and TLS 1.0 protocols to be used to connect with their websites. But if you are still using a browser which is compatible with TLS 1.1 or TLS 1.2 then you might see that some website is not working in your browser, nonetheless, the connection between your browser and other websites is not secure and you can be hacked.

What action do you need to take

Okay, It's simple. You need to use either TLS 1.1 or 1.2 for your browsers and disable SSL 2.0 , SSL 3.0 and TLS 1.0 in browser. Though TLS 1.2 is highly recommended but not all websites are still compatible with higher TLS protocols. So, if you disable TLS 1.0, you might see, still many website is not opening. So target is to disable SSL 2.0, SSL 3.0, and TLS 1.0 and enable TLS 1.1 and TLS 1.2 in your browsers.

One good news is, if your browser is up-to-date irrespective of which browser you are using, might not have to do anything. As in all latest browsers, latest TLS protocols are enabled by default and are using higher TLS protocols wherever possible. Please check whether you are using latest web browsers or not. If yes, then you can skip below actions.

If you are reading this article then high chance is your browser is already supports TLS.

If you are using older browsers for any reason and you want to enable higher TLS protocols please go through below steps as per your browser. But my recommendation would be to upgrade your Operating System and Browsers as soon as possible.
