check SSL/TLS Capabilities of Your Browser

TLS 1.3 is made available by Firefox.
To check if you already use it, go to about:config, accept warning, and search for security.tls.version.max

If you have it, the number is 4. If the number is 3, you have TLS 1.2 version. Double-click to change value to 4.

Progressively, Firefox makes TLS 1.3 available for all users.

Hmmm last time I really checked, FF27 mis-behaved and reset a 4 value to SSL3 (zero value). I will check again and report.
How about a link to the particular mozilla atricle.

FF27 still rolls-back, but now to TLS1.0.
FWIW both minimum and maximum should be 3
about:config --> search ssl and then tls.
