My bank has just advised that after Jan. 8, 2015 my browser has to use TLS 1.0 as its encryption method. I can't for the life of me find out what encryption method Firefox uses.

I believe the Firefox 34 release tomorrow will have TLS 1.0 be the minimum it will use and not SSL 3.0 security.tls.version.min = 1 = TLS 1.0 as 0 was SSL 3.0


Not on my computer to check.

Note that Firefox 34 is out.

See also:

0 means SSL 3.0, 1 means TLS 1.0, 2 means TLS 1.1, 3 means TLS 1.2 etc.

Yeah I noticed after that Firefox 34 came out today instead of Tuesday per usual.
