Eh, I’ve been using a couple (a local exit for targeted searches and a remote one for general usage) of gluetun containers for ages. Hook apps to the proxy server or tun (and containers to the relevant network). Does the same, more versatile, likely more secure, lot of eyes on gluetun. FoxyProxy lets me set rules based choices in firefox, or manually override in a couple clicks. Still, good for them and the untechnical, I guess.
