Mozilla released Thunderbird 59 beta in February 2018. This article is about Thunderbird 52, which is in widespread use and was released to users in April 2017.

Mozilla Thunderbird 52 is a free full-featured and secure email application and chat client that includes an RSS feed reader and newsgroups option. Manage as many email accounts as you want from one convenient location efficiently and with style, while Mozilla Thunderbird filters away the junk mail.

Thunderbird 52 Features

Mozilla Thunderbird 52 brings together privacy, speed, and the latest technology. Features include:

  • Mail Account Setup Wizard. You no longer need to know your IMAP, SMTP and SSL/TLS settings. After you enter your name, email address, and password, the wizard checks Thunderbird and selects the correct settings.
  • Attachment Reminder. When your outgoing email mentions attachment or a similar term, Thunderbird reminds you to add the attachment before you send the email.
  • Multiple-Channel Chat. Chat with your contacts from Facebook Chat, Google Talk, IRC, Twitter or XMPP messaging application. Search past conversations and received emails from your contacts.
  • One-Click Address Book. Add people to your address book by clicking on the star on the message you receive. Use two clicks to add additional information or a photo.
  • Personalized Email Addresses. If you've dreamed of a personalized email address, you can sign up for one right in Thunderbird. The email service sets it up automatically for you to use.
  • Tabbed Email. Thunderbird took a cue from its sister-app Firefox and added Tabbed email. When you open emails in tabs, you can quickly jump between them.
  • Web Search Inside Thunderbird. You don't have to leave Thunderbird to search the web. Type your search term in Thunderbird's search field and select from several different search providers. If you run across an unfamiliar term or concept in an email, right-click it and select Search the Web for to start a search.
  • Search Tools. Thunderbird indexes your emails and chats so you can search them quickly. The results appear in a separate tab for easy reference.
  • Quick Filter Toolbar. Type words in the Quick Filter search box for almost instant results. You can also filter by New Messages, Tags, or people in your Address Book.
  • Activity Manager. Thunderbird's Activity Manager is the place to look for a synopsis of the interactions between your Thunderbird browser and your email provider in one place. 
  • Quick Message Archive. If you don't need an email message but don't want to throw it away, send it to the archive folder system by hitting the A button.

Customize Your Thunderbird Experience

Thunderbird offers a lot with the initial download, but you can customize your email experience in several ways:

  • Personas and Themes. Think of personas as lightweight skins that change the look and feel of Thunderbird. Hundreds of personas are available for download including ones for recent movies and famous landmarks. You can also download Themes that change all the icons in Thunderbird.
  • Smart Folders. Anyone with multiple email accounts will appreciate Smart Folders that combine special folders like your Inbox, Sent or Archive folders. Instead of going to multiple Inbox folders, you can make a single stop.
  • Add-ons Manager. You don't have to leave Thunderbird and go to an add-ons website. From the Add-ons Manager, you can see descriptions, ratings, and recommendations of available add-ons that add functionality to Thunderbird.
  • Filelink Large-File Management. Set up Filelink to handle the upload of files that are too large to attach to an email. Select from popular large-file attachment sites such as Box, YouSendIt, and Ubuntu One.

Security Features

  • Phishing Protection. Thunderbird protects you from being tricked into handing out your personal information by marking potential phishing attempts. It also notifies you when you click on a link that will take you to a website that is different from the one indicated in the message.
  • Privacy and Do Not Track. To protect your privacy, Thunderbird automatically blocks remote images in emails. Thunderbird also provides a Do Not Track option associated with Search the Web. It can be used in other requests through the use of an add-on.
  • Automated Updates. Thunderbird notifies you when a security update is available.
  • Junk Mail Filters. Each time you mark an email as spam, Thunderbird learns from your action. The service's popular junk mail tools have been updated to stay ahead of spam.
