Thunderbird-Hilfeforum

Many times now, I have needed to change folder views to 'Unthreaded', ditch 'Correspondents' in favour of 'From' and 'Recipient' and arrange my emails in descending date order. Every time I create a new folder, I need to go through the same routine. Every time I download a new version of Thunderbird, all my folders are changed back to 'Threaded' and 'Correspondents' and are in Ascending date order, so I have to go through the whole process again. What I need is a simple 'global' setting in a menu, so that I can change the settings for ALL my Thunderbird folders in a simple series of clicks, without needing to go to each folder every time. Better still would be a 'once for all' fix that would prevent Thunderbird changing my settings every time I download a new version. There must be thousands of Thunderbird users who share my frustration with what is lotherwise an excellent email program. Please fix it!
