Notice the script sent before <!doctype html>

Funky! Same thing is happening on Blink and WebKit browsers. Not a WebCompat issue but a very very very broken site.

The thing is that window.location.replace(''); sends back a undefined but the redirection still happens and enter an infinite loop.

I wonder if it should be blocked in browsers.

Firefox Mobile don't stop infinite loop.

Tried a tweet http://twitter.com/webcompat/status/720083280956010496

There is also a form at https://www.franquiaportaldacidade.com/contato Needs someone speaking Portuguese though.

Switching to contactready
