Ever since I stupidly let Thunderbird 'update' to 140.5esr 64bit the date format has been wrecked. The program now forces the plain weird US date format of Month-Day-Year. I hoped that this obvious error would be fixed but it's been rather a long time now and the problem - and IT IS A PROBLEM - hasn't been addressed. It looks like Thunderbird is following Firefox in making each version worse. Whilst I switched to Pale Moon long ago there is as yet no fork of Thunderbird. If I were still on Windows for internet use I would just install an older version alas I do not know how to do this on Linux (Q4os Trinity) PLEASE fix this problem. I am far from the first to point this massive mistake out.

I am genuinely grateful to the people who work on these projects but a little more effort on actually being able to use the programs would be a substantial advance.
