Ubuntu Brings Thunderbird 91 to Older Releases to Fix Security Flaw

Thunderbird 91 is being back-ported to Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. A security vulnerability affecting the Thunderbird 78.x series both builds offer is being actively exploited in the wild. But as upstream support for Thunderbird 78.x soon ends the flaw is unlikely be patched soon. For an Ubuntu LTS release that’s a major issue. So to ensure its users are not affected, Ubuntu developers are backporting the latest Thunderbird 91 release (which is an extended support release, thankfully) to Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 21.04. This isn’t the first time Ubuntu has needed to do
