This created plenty of confusion as to whether Mozilla was, in fact, dropping the Thunderbird project altogether. In 2015, Mozilla announced that it would separate the infrastructure of Thunderbird and its popular Firefox web browser. However, over recent years, there’s been plenty of talk about whether Thunderbird has a future, and whether it’s up to the job in our increasingly mobile world. It also has hundreds of add-on apps available that allow users to customize their email client and increase functionality. It’s completely free, open source, and runs on a variety of operating systems including Linux.

Mozilla’s Thunderbird gets a lot of love in the world of email.
