Maybe you can try the Shadowsocks browser app from the App Store.
It has a public SSH tunelling proxy. You can also use your own server settings if you have one.
Works pretty well for basic web stuff.
Thanks. That's cool & would alleviate the pain a bit I guess. The thing that drove me nuts is that Slack was blocked, but I guess I could have run that from within a private browsing app like the one your recommended.
