Rambox is an electron app which you can use to always open certain tabs like Gmail, WhatsApp, and other services which you login to using accounts. Its bascially a limited version of a browser which you use to check your accounts, mainly messaging ones like Gmail, WhatsApp, Slack etc. It does nothing magical other than opening the webpages.
But Rambox doesnt support Socks5 proxy. It only supports HTTP/S proxy. I want a similar app that supports Socks5 proxy with authentication. I can find similar products at https://alternativeto.net/software/rambox/ , but I can't easily know which of these support a Socks5 proxy.
