There has been an ongoing problem with the latest updated binary showing up on the main thunderbird.net for days after it has been released. This is a serious problem because users cannot access patches that keep them safe from security vulnerabilities. I've contacted the team several times and was told this was a replication issue with the site or the CDN. The issue still hasn't been fixed. Today Feb 4th is yet another example. At the main Mozilla security advisory I see the release of TB 135 and TB ESR 218.7. https://www.mozilla.org/en-US/security/advisories/ When I go to Thunderbird Releases site https://www.thunderbird.net/en-US/thunderbird/releases/ and the main page and click on downloads, I see the OLD 128.6.0 This is a persistent problem and it makes the users of Thunderbird less safe, please fix this.
