Where can I find a binary cache for Thunderbird with CUDA enabled now?

Thunderbird compiling from source was one of the packages that caused me the most pain - alongside PyTorch with CUDA. Multi-hour builds that would sometimes OOM and crash my system.

Two solutions that helped me:

  1. Switch to thunderbird-bin and firefox-bin - these just unpack the official Mozilla binaries, so no compilation needed. Much faster and just as functional.

  2. Use the new CUDA cache URL - the official cache moved to https://cache.nixos-cuda.org/. Here’s my cache configuration.

I also ended up building a local Harmonia cache server for my fleet, which I wrote about here, but the -bin variants solved the Thunderbird/Firefox problem immediately.
