Linux is a can of worms due to the many distributions. The executables we build on a current version of Mint 20.2 (as of August 2021) require GLIBC 2.31 to run. Thunderbird can run on earlier versions of GLIBC. See Distrowatch for a list of distributions and click on the respective distribution link to see the GLIBC version.
Note Betterbird and Debian's/Ubuntu's Thunderbird build use EGL 1.5 graphics API whereas Mozilla-built Thunderbird uses GLX 1.4 which can lead to blurry fonts.
Due to popular demand, we're providing a Mac build. This is compiled on an Intel Mac under macOS 12 "Monterey". We've also tested it on macOS 10 "Catalina". We had feedback that it also works under macOS 13 "Ventura" both on Intel and M1/2 (ARM) hardware. Feedback welcome on what works and what doesn't.
