Today, I’d like to announce Homebrew 5.0.0. The most significant changes since 4.6.0 are download concurrency by default, official support for Linux ARM64/AArch64, timescales for deprecating macOS Intel and removing macOS Gatekeeper bypass behaviours.
Shame on you, Homebrew, for effectively killing FOSS apps from casks.
Casks are as a rule GUI applications. So if you want to install Firefox with homebrew would need to install it via a cask.
