Mozilla Thunderbird email client released new major 91.0 version with many new features and improvements.
Thunderbird 91.0 now runs in multi-process (e10s) mode by default, which offers many advantages in responsiveness, stability, performance, and security.
For macOS users, the release adds native support for computers with Apple silicon CPUs. There are also Latvian language support, new user interface for adding attachments, etc.
The ‘Account Setup’ has a new look and finally move to new tab instead of a floating dialog. It also adds ability to detect and set up CalDAV calendars and address book during setup.
The new version also brings improvements to Calendar, such as remote calendar auto-detection, ‘Edit’ option in event context menu, double-click to open .ics files, and import filter and sort items.
And a warning popup will appear when either trying to spend a reply to a likely non-existant email address such as “[email protected]”, or public recipients of a message exceeds threshold.
Other changes in Thunderbird 91.0 include:
- Beta-level support for Matrix servers chat.
- Enable redirect of messages.
- PDF.js viewer support.
- Allow showing empty CC/BCC rows in compose window
- Allow pinning folder views to the Folder Pane
- And much more!
