How to install Firefox Developer edition via Homebrew?

Question

This is how to install Firefox via Homebrew:

brew install --cask firefox

But how to install the 'Firefox Developer edition'?

Everything I tried fails with 'Error: Cask '...' is unavailable: No Cask with this name exists.'

brew install --cask firefox-developer-edition
brew install --cask firefox-nightly

What's the correct command?

Answer 1

I've finally found a solution.

Lots of commands on the internet were outdated.

These 2 commands worked for me in 2022 (still working in 2024)

brew tap homebrew/cask-versions
brew install --cask firefox-developer-edition
