I’m going to explain how you can remove a friend from your friends list in your Overwolf chat.
First, download and install Pidgin from here. Once you have this installed, run Pidgin go to Accounts and choose Manage Accounts, Press Add.
You will receive a page that looks like this:
Under the Basic tab:
Set the Protocol to XMPP
Fill in your username and password.
Type in Domain – xmpp.overwolf.com
Under the Advanced tab:
Set the Connect to port – 5222
Set the Connect to Server – xmpp2.overwolf.com
Set the File transfer proxies – proxy.eu.jabber.org
Click add. This will load up your Overwolf chat inside Pidgin and let you right click on a user and then remove said user from your friends. When you load your Overwolf chat again, they should not appear again.
