11 months after the publication of the last significant issue mail client release , developed by the community and based on Mozilla technologies. The new release is categorized as a long-term support release, with updates released throughout the year. Thunderbird 78 is based on the ESR release codebase . Release available for direct only , automatic upgrade from past releases to version 78.0 is not provided and will only be generated in version 78.2.
All :
- Dropped support for XUL plugins. Only add-ons written using the API are now supported (similar to WebExtentions).
- Built in experimental (not enabled by default) support correspondence and certification of letters with a digital signature based on OpenPGP public keys. Previously, this functionality was provided by the Enigmail add-on, which has been deprecated in the Thunderbird 78 branch. The built-in implementation is a new development, which was prepared with the participation of the Enigmail author. The main difference is the use of the library , which provides OpenPGP functionality instead of invoking the external GnuPG utility, as well as using its own keystore, which is not compatible with the GnuPG key file format and uses a master password for protection, the same as that used to protect accounts and S / MIME keys.
Thunderbird's previously available native S/MIME support has been retained.For
support OpenPGP in the settings, you should set the variable mail.openpgp.enable. Add-on users it is recommended to stay on the Thunderbird 68 branch until the automatic update is generated to ensure the correct conversion of existing encryption settings. Enabling OpenPGP by default is scheduled for the release of Thunderbird 78.2.
