SSL TLS 1.2 not supported on websites

Hello

When going on your web sites that are encrypted (SSL), TLS 1.2 is not supported.
The problem is that is you want your browser secure (for internet banking for instance), you need to set a high level encryption (TLS 1.2), and then your browser does not work on lesser secure connections (SSL 3 for instance).
Would it be possible to activate TLS 1.2 support on your web servers ? It's not much work, makes your site more secure, and i don't need to change browsers to use your site .
Thank you for taking the time to read this.
Keeep up the good work.
