@taylan Gentoo does now offer more pre-compiled binaries, but they're built on computers running proprietary software and for stuff like firefox do things like compile with the telemetry USE flag enabled - so I don't use them.

Binary package support in portage has been mature for years, it's just a matter of compiling the binaries.

I compile everything from source and I have no problems doing so, as I don't try to compile garbage.
