I have been looking for a portable solution for a Mozilla Thunderbird app but unsuccessfully so far. It is vital for me to keep Thunderbird's configuration so after a fresh OS install, once I install Thunderbird again I would have all my email accounts connected to the thunderbird app and would not need to reconnect them again to the freshly installed Thunderbird package.
Now how can I do that? I am completely new to Linux and do not have a clue which files I should save in order to achieve my goal.
