slijedio sam i ove upute preko registrya, nije pomoglo
https://support.mozilla.org/en-US/questions/1323685
instalirao sam staru verziju 68.x.x
prilikom pokretanja javlja mi ovo :
You have launched an older version of Thunderbird" error. It goes on to say, "A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version...".
nudi mi EXIT i Create new profile
Ako izaberem kreiranje novog profila, pokrene se TB i nudi kreiranje profila ALI ne šjivi ni 5% onu mapu THunderbird od 17Gb koja je iskopirana prije pokretanja
