My bank is eliminating TlS (Transport Layer Security) numbers Tls1.0 and Tls 1.1 and will switch to Tls 1.2. My bank told me I had to enable it manually. However searching Mozilla/Firefox I could find no reference to TLS. Does that mean I will have to switch browsers when I want to get Estatements from my bank? Thank you

Yes, current Firefox releases support TLS 1.2. (TLS 1.3 is still under development)

There are TLS settings prefs on the about:config page that specify the minimum and maximum TLS version.

  • security.tls.version.min = 1
  • security.tls.version.max = 3
  • 1 means TLS 1.0; 2 means TLS 1.1; 3 means TLS 1.2; 4 means TLS 1.3;
