Software Update: Mozilla Thunderbird 91.11.0

In addition to version 102.0, the Mozilla Foundation has also released version 91.11.0 of Thunderbird. Thunderbird is an open source client for e-mail and newsgroups, with features such as support for various mail and news accounts, a spam filter, spell checker, and a customizable appearance. In version 91 has included a warning when an email is sent to a potentially non-existent address, or when there are too many addresses on a public address line. There is also support for CardDAV and a native client for a Mac equipped with an Apple Silicon processor. This release fixes two bugs and some security vulnerabilities.
