My mom does Mary Kay and she just got an Email saying.


Dear Nadine,

Chase Paymentech, Mary Kay’s outside vendor that handles Independent Beauty Consultants’ card-payment transactions, is updating their payment processing systems to use the TLS 1.2 security protocol. As a result, you will need to update your web browser no later than Nov. 20, 2017, to ensure that the Company is able to process your online ordering card-payment transactions.

Please update your system to enable TLS 1.2 on your web browser following the simple instructions outlined below.

Mozilla Firefox

   Open Firefox
   In the address bar, type about:config and press Enter
   In the Search field, enter tls. Find and double-click the entry for security.tls.version.min
   Set the integer value to 3 to force protocol of TLS 1.3
   Click OK
   Close your browser and restart Mozilla Firefox

Is this safe to do I have never heard of a company telling customers to do this before.

We already have "security.tls.version.fallback-limit;3" so the defaults are secure and you need not change anything. Just keep Firefox up to date and this will be taken care of by the developers in most cases.
