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!

This could very well be a bug in the current beta build. In that case, please report it to the publisher. We just make it portable.
Please note that we do not recommend using Thunderbird Portable Beta packages for everyday use. They are for testing purposes only.
Sometimes, the impossible can become possible, if you're awesome!
Where can I contact the authors of the software?
