Works nice if you have a paid subscription. Though, would be wonderful to implement reverse version of the split-tunneling, when only sites specified are routed through the VPN.

E.g. if I'm ok with revealing my ip to most of the sites I visit, or I already route all the home network traffic through a local Proton server, but I want to completely hide my location from selected few sites. For them I'd like Firefox to automatically route the connection through a secure-core network. Currently it is only available when you manually connect and disconnect the extension as needed, and I often forget to do so.

Otherwise, a very useful extension
