I can't use the Inspector or other developer tools to check what goes on because the debugger gets activated by some JS file that contains a debugger statement.

You should notice your CPU usage going high for just displaying that page.
</p><p>You can also try to type a few characters in the username text box ("nome de utilizador") and you should observe it takes some seconds to display each character, because the browser is heavily loaded.
