Pinning folder views to the Folder Pane.Some other new features or notable changes you can find in Thunderbird 91: I’d gotten into a habit of adding my email accounts in a specific order so that the one I want to show at the top, shows at the top. Y’know which change I’m most excited for? The ability to change the order of mail accounts in mail sidebar (albeit not from the sidebar itself but the accounts UI, using drag and drop). If you’re a big user of the Thunderbird’s calendar capabilities, chances are you’re going to love all of these rich, productivity-minded changes. ics files, registering as a handler for webcal: URLs, and showing a handy colour-coded category dropdown when creating new events. This includes remote calendar auto-detection, handling of. Thunderbird’s set-up wizard has a new look and a number of new features, plus a location: you now set-up and connect accounts in a new tab rather than yet-another floating window/dialog (which is something Thunderbird is infamous for).Ī clutch of enhancements to Thunderbird’s built-in calendar feature (yes, it has one these days) also features. Multi-process should result in a performance boost too.

Quite a lot, based on the sheer length of the official Thunderbird 91 release notes!Īnd it seems that this release is such a major upgrade that users of Thunderbird 78 -you’re not misreading that is the preceding version number- can not upgrade directly to the new build, not yet anyhow.Ī future release will re-enable in-place upgrades to allow users to upgrade Thunderbird 78 to 91. Fans of the Thunderbird email client will be eager to go hands-on with the latest release, which is now available for download.
