Betterbird: System Requirements


Operating Systems

Windows Recommended Hardware


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.

Supported versions, for example:
Linux Mint 20
Ubuntu 20
Debian 11 "Bullseye".

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 was compiled on an Intel Mac under macOS 12 "Monterey". We've also tested it on macOS 10.15 "Catalina". Feedback welcome on what works and what doesn't.
