You can use a plugin like this one for Firefox. Generally my preference is for redirecting to be done client side rather than for me, or prepared as an alternate option. Like in the cases of Youtube -> Invidious, Reddit -> Redlib, sometimes the service is offline which makes it hard to know what was originally linked.

Might be worth looking at farside.link

I know of LibRedirect, which is the kind of thing you're looking for
