I am using Thunderbird (3.1.20) on Mac running OS 10.7.5, considering El Capitan upgrade how can I update ThunderBird?
Considering updating the OS on my Mac, but have not updated Thunderbird want to find out the best way to do this. Should I try to update Thunderbird first? Can I do this without loosing emails that are organized in different folders currently?
