Thunderbird 52.0 released: find out what is new
Thunderbird 52.0 is out. The new version of the desktop email client for Windows, Mac and Linux devices was released on April 4, 2017 to the public.
The new version of the email client is a major new releases, as indicated by the version. It replaces the previous version Thunderbird 45.8.0.
Thunderbird installations and portable copies will pick up the new update eventually. You can check for updates with a click on Help > About Thunderbird. The new version may not be available yet via the automatic update system of the email client.
The new version ships with a massive list of new features and changes. Probably the biggest change in the new version is a change in how images are handled by Thunderbird.
The way images are included in a compose window has changed. Images are now included as data URIs and not as references to parts of other messages or operating system files. This allows better interoperability with office packages such as MS Office or LibreOffice. Images linked from locations on the internet will no longer be downloaded and attached to the message automatically.
So, image links that point to Internet locations won't be downloaded anymore automatically by the email client. This should deal with tracking pixels attached to emails.
The team notes that images may be downloaded on a "per image" basis using the image properties dialog. Thunderbird users who want to restore the former status quo may do so as well:
- Select Tools > Options.
- Switch to the Advanced > General tab.
- Select Config Editor there.
- Use the search for to find mail.compose.attach_http_images.
- Double-click on the preference to set it to true.
