Thunderbird 78.7 released with fixes and improvements

Mozilla releases Thunderbird 78.7, an application update that includes a number of general fixes and new API improvements. It is now available for download for Windows, Mac OS and Linux.

Thunderbird is my favorite e-mail program. I use this application on every computer and operating system I use. It is stable, contains all necessary functionality, supports add-ons and comes with a handy RSS reader. I have been using Thunderbird for years and have never felt the need to look for an alternative.

Thunderbird 78 no longer supports the classic XUL add-ons, but does include some of their out-of-the-box capabilities. In Windows, for example, you can minimize an application on the taskbar.

The following amendments were made to the Annex.

What happens in Thunderbird 78.7.

  • New API extensions : Link API now allows you to edit posts and templates as new posts
