Thunderbird 78: Update to 91 enables JavaScript via PDF reader! In the last days and weeks I have received various information about Thunderbird from blog readers, which I would like to include in this article and post on the blog. But both and Bleeping Computer reported a few days ago that the change to version 91 is done via update – probably runs in waves. I myself am still on version 78.x and an update search does not yet offer Thunderbird 91 after. So far, Thunderbird 78.x users have not been upgraded to version 91 when checking for updates. Currently we are at Thunderbird 78.14.0 (see Thunderbird 78.14.0), but there is already the Thunderbird 91 development branch (see Thunderbird 91.2.0).Īt Bleeping Computer I found the following: As of October 5, 2021, 85% of Thunderbird users were using client version 78, and only 9% had manually upgraded to 91. The development branch 78 of Thunderbird will end soon – because with Thunderbird 78.15.0 the development ends (Tom pointed it out here).

Migration from 78.x to Thunderbird 91 starts soon
