I’m assuming you means from Chrome’s extension store (not sure why they call it)

While they can be installed manually with extra steps, there are also other browsers out there.

Don't worry, Google will just "accidentally" break compatibility for those extensions in a way that's totally not just anticompetitive behaviour, because they've never done that sort of thing, like breaking other Google properties undermine Firefox before, no sir.

They've made it so you basically can't keep non Chrome store extensions installed on Windows. At least not without a nag every day.
