For those that don't use Outlook, Thunderbird is one of the best options for email. Out of the box, Thunderbird is a strong candidate for just about any use. However, if you're looking for some added security for your email client, you might want to look into the many and varied extensions available for the open source email client.
But not every extension is created equal. I have combed through the list of security-related Thunderbird extensions and have found five that are the most useful in creating a significantly more secure email experience. Though not each of these will be usable by everyone, each has its place in the realm of securing your email. Let's dive in and find out which of these apps is suited for you.
