@ClandestineOne No, it is actively maintained and the devs are doing a great job at it.. (it's basically firefox with hardening and malware removed)

$ guix show icecat
name: icecat
version: 91.7.0-guix0-preview1

The pre-built binary is not maintained since 2019 due to the unsustainable resource requirements to provide the binary that is not going to help anyone in terms of distro packaging and devs recommend to use distros that are able to package it such as GNU Guix (which can be installed on any distro as second and independent package manager that can be uninstalled cleanly e.g. `apt-get install guix && guix install icecat`)

Let me know if you need help with it on linux, for windows there is a chocolatey https://community.chocolatey.org/packages/icecat
