Looking for a smart way to archive your e-mails from Thunderbird? There are many advices like copy your “/home/(username)/.mozilla/…” directory, which (in my opinion) are not very smart. After googling quite a while, I found a very cool TB extension called SmartSave and it lives up to its name! It needed less than ten seconds to export 1900 mails with a total size of 150 MB. I like it!
