Nothing happened, except that your internet connection started working OK, I am sure you can connect electrum to its own servers without the need of opening any of the browsers, TOR ,Firefox, Google Chrome, Safari , Electrum should connect to its servers even if you click it (for example I in Linux click Applications-Internet-Electrum and it connects) I don't have any other thing open, I just have a good internet connection running. There's no tie between electrum and TOR or whatever other browser that is. You can give it a try and let me know, but I am sure it will connect as long as you have a good working internet connection.
He probably has the proxy set for Electrum.
