I'm trying to configure a tor proxy so I can use the tor feature, and to do this I have to change/reconfigure the server. Also, is it possible to use tor with a public server? I don't have my own full node or personal electrum server at this time, so public is my only option. I'm wondering if it's possible to use an external proxy to use tor with a public server.
You can try Wasabi Wallet, it uses Tor by default and you don't connect to any public servers since it uses BIP157/BIP158 style block filters.
