It's free and it works, plus from what I've heard Proton has a decent reputation.

Great for bypassing restrictive ISPs.
It needs an inclusive mode (whitelist) for split tunnelling; sometimes the use case is reaching a few select sites.
It'd be nice to have a "just this tab" option.

works as intended

A great app from a brilliant company. The extension has all the core features of the desktop/mobile app equivilent, and is quick and easy to use. The benefit is you get a VPN connection within the browser while other apps open stay on your original network.
Proton is fully encrypted and cares about your privacy – Something that cannot be said about many VPN providers

funktioniert alles einwandfrei unter openSUSE Tumbleweed :-)
