I cannot figure out how to enlarge the print in the window that displays the list of e-mails. I have found a place to specify font and have tried that, but that does not affect anything in the window I have mentioned. On my old computer (Win 10, 64 bit), I found the font on that window large enough. Not now with my new computer (Win 11, home). I suppose I am running an earlier version of Thunderbird on the old computer? (I haven't yet found the 'about' tab for Thunderbird -- not Firefox, to tell me what version I am running.)
