On top of that, users can now copy entire folders within both local folders and mail server accounts, while a \u201cReset Folder Order<\/em>\u201d option has been added to the folder pane for those who want to undo custom sorting quickly.<\/p>\n\n\n\n Not everything stayed the same, though. The \u201cCopy Message Location<\/em>\u201d option has been removed from the mail context menu, as part of Thunderbird\u2019s ongoing effort to simplify the interface.<\/p>\n\n\n\n Regarding fixes, the list is massive. A wide range of issues have been addressed, from Fastmail calendar integration breaking due to missing OAuth settings to notification sounds ignoring the system’s do-not-disturb mode.<\/p>\n\n\n\n Linux users in particular will notice improvements, such as the close caption button now working properly when the mouse is in the screen corner, along with smoother handling of dark message mode toggles and tab navigation.<\/p>\n\n\n\n Other fixes tackle everything from English folders being created in non-English installations, to \u201cmailto:<\/em>\u201d links failing to open on Microsoft Store installs, to contact photos in WebP format not displaying from CardDAV servers.<\/p>\n\n\n\n Performance issues also got attention, with developers resolving slow initial startup times and UI lag while messages are downloaded.<\/p>\n\n\n\n Newsgroup users will see changes as well. Folders now maintain alphabetical order by default, and Thunderbird should reconnect more reliably after a connection loss. The update also corrects problems with posting failures, incorrect folder archiving for RSS feeds, and several quirks with filtering, quoting, and message list behavior.<\/p>\n\n\n\n Finally, the release rounds things out with visual and UX improvements plus a batch of security fixes.<\/p>\n\n\n\n For more information, see the announcement<\/a>.
