- Firefox may be more prevalent on those using Linux, since FF is less “corporate” than Chrome or Edge.

- People using Linux are probably putting Linux on old machines that had versions of Windows that are no longer supported.

However, what I can’t say next is “PSUs would get old and stop putting out as much” because that doesn’t tend to happen. They just die.

Those running Linux on some old tower may hook up too many devices to an underpowered PSU which could cause problems, but I doubt this is the norm.

If it’s not PSUs, what is it? It’s not electromagnetic radiation doing the bitflipping because that’s too rare.

Maybe bitflips could be caused by low-quality peripherals.

People also don’t vacuum out laptops like they used to vacuum out towers and desktops, so maybe it’s dust.

Or maybe it’s all a ruse and FF is buggy, but they don’t have time to figure it out.
