Proxies

Session Splitter profiles accept HTTP, SOCKS 4, and SOCKS 5 proxies.

The format used for proxies-
IP: Port

At the time of profile editing, username and password are not required.
When you start the session for that profile and visit any website, the browser will ask for ‘Username’ and ‘Password’ for that proxy.
Just enter the username and password in the respective fields and hit the ‘Sign in’ button. If you want to save passwords in ungoogled chromium, learn here.

You can Enter more than one proxies for a profile. Enter each proxy (with the port) in a new line, as shown in the screenshot below.
