Manage your emails with numerous powerful features. The tool imports your mail and contacts from your Outlook or Mail account. Offers an easy way to add contacts and detailed info on them to your address book. Filters your mail into separate folders and inboxes, reminds you about forgotten attachments, provides multiple-channel chat for real-time conversations, creates personalized email address easily, and more.
I have been using Mozilla Thunderbird for several years now. There are some reasons it has become my favorite email client. Firstly, I sometimes switch between Linux and Windows, and for the multi-platform usage Thunderbird is ideal, since you do not want to use two different clients. Secondly, this application not only manages your emails but also does many other things. And moreover, its features can be expanded by using any from a long list of available add-ons. In addition, if the application's interface seems a little plain to you, it is possible to change its look by applying any of the available skins.
If you are already familiar with Microsoft Outlook, starting to use Thunderbird will surely be an easy task. Moreover, you can use the tabs in the interface to display messages or access other services. Obviously, you need to set an email account before you can start managing your mail inbox. Mozilla Thunderbird will make this task very easy and even offer to create a new account for you. Fortunately, you can set various email accounts, which you can compartmentalize by using different folders. Not only mail accounts can be managed but also chat accounts and RSS. Fortunately, it supports multiple chat servers, such as XMPP (Jabber, Facebook), Google Talk, IRC, Twitter and Yahoo. Finally, the built-in calendar (Lightning) allows managing your events and triggering alerts, what is more, your calendar can be stored locally or on a server.
The program uses a fast rendering engine, so you will have almost instant access to the contents of your messages. And talking about contents: this program can make dealing with spam easier, as its developers have implement Bayesian algorithms that allow it to actually learn from your decisions.
All in all, Mozilla Thunderbird is undoubtedly one of the best email clients. It is constantly being developed by a legion of devoted followers; and fortunately, the program can connect to the Internet and check your version so that you are always up-to-date. Perhaps, my only objection is that I find that chatting is somewhat slow compared to other messengers.
v60.0 [Aug 17, 2018]
- new: When writing a message, a delete button now allows the removal of a recipient. This delete button is displayed when hovering the To/Cc/Bcc selector.
- new: Many improvements to attachments handling during compose: Attachments can now be reordered using a dialog, keyboard shortcuts, or drag and drop. The "Attach" button moved to the right to be above the attachment pane. The access key of the attachment pane (e.g. Alt M, may vary depending on localization, Ctrl M on Mac) now also works to show or hide the pane. The attachment pane can also be shown initially when composing a new message. Right-click on the header to enable this option. Hiding a non-empty attachment pane will now show a placeholder paperclip to indicate the presence of attachments and avoid sending them accidentally.
- new: "Edit Template" command. This also solves various problems when saving as template (duplicates created, message ID lost).
- new: "New Message from Template" command.
- new: Allow changing the Spellcheck Language from status bar.
- new: Light and Dark themes.
- new: WebExtension themes are now enabled in Thunderbird.
- new: A default startup directory in the address book window can now be configured.
- new: Individual feed update interval.
- new: An option under "Tools > Options, Advanced, General" now allows to select whether date/time display will follow the application locale (adjusted by operating system's format settings for that locale) or the locale selected in the operating system's regional settings. In other words, an US English Thunderbird can use, for example, German formats.
- new: OAuth2 authentication for Yahoo and AOL.
- new: FIDO U2F support.
- new: Thunderbird now allows the conversion of folders from mbox to maildir format and vice versa. This is an experimental feature that needs to be enabled by setting the preference mail.store_conversion_enabled. Note that this functionality does not not work if the option "Allow Windows Search/Spotlight to search messages" is selected.
- new: Calendar: Allow copying, cutting or deleting of a selected occurrence or the entire series for recurring events.
- new: Calendar: Provide an option to display locations for events in calendar day and week views.
- new: Calendar: Provide the ability for sending/not sending meeting notifications directly instead of showing a popup.
- new: Calendar: Option to select the target calendar when pasting an event or task.
- new: Calendar: Allow email scheduling for CalDAV servers supporting server-side scheduling.
- new: Thunderbird Chat now contains multiple built-in message themes.
- changed: IMPORTANT: Add-ons not marked as compatible with Thunderbird 60 by their authors will be disabled (this can be reverted via preference extensions.strictCompatibility).
- changed: IMAP: When after sending a message storing that sent message fails, the message can now be stored in a local folder.
- changed: Add-on options can no longer be configured from the Add-on Manager page. A new menu item "Add-on Options" is now available on the Tools menu.
- changed: When messages are composed in paragraph format, "body text" and split mail quotes are converted to paragraphs when pressing the enter key.
- changed: "Edit As New Message" will now use the account's default compose format, either HTML or plain text ignoring the format of the message. Plain text messages will be converted to HTML and vice versa. Then using the modifier, the format choice will be reverted.
- changed: The "Edit Draft" command now also honors the use of the shift key to convert HTML to plain text or vice versa when editing a draft.
- changed: The plain text to HTML conversion has been improved where such a conversion is necessary for "Edit As New Message" or when the shift modifier is used for "Edit Draft" or "New Message from Template".
- changed: During address entry, the matching part of the address is now shown in bold. Preference mail.autoComplete.commentColumn allows to display the address book where the address is stored.
- changed: When attaching a message via drag and drop, the subject of the message is now used as attachment name instead of "Attached Message".
- changed: Better address book photo handling: Photos can be added by drag and drop and a copy of all photos will be stored in the Thunderbird profile.
- changed: On first start, Thunderbird now shows the account setup dialog, no longer the account provisioner dialog.
- changed: Thunderbird follows Firefox' Photon design with rectangular tabs and many other theme improvements.
- changed: When customizing the From: address, Thunderbird will now use this address for the SMTP "MAIL FROM" command. Previously the address configured in the identity was used. The preference mail.smtp.useSenderForSmtpMailFrom allows return to the previous behavior.
- changed: Native notifications on Linux are now re-enabled.
- changed: Thunderbird now uses Mozilla's latest proxy technology (add-on FoxyProxy now supported).
