I am using Thunderbird 54.0b2 (32 bit) portable (20170524131922)
After the last update the date-time format of the e-mails has changed to MM/dd/yyyy as seen in the upper part of the image. The date-time format of the OS is set in dd/MM/yyyy (as seen in the lower part of the image).
I need an advice how to change the date-time format of Thunderbird to the one set in the OS.
Thank you in advance!
