When going in my account page and Edit My Account, I can't change my email address. I can replace the old one by the new one but when pressing the Save button, the loading indicator animation doesn't stop. I left it running for hours, it doesn't save the new email address.
I'm on Xubuntu 13.10, using Firefox 27.0.1 and Chromium 32.0.1700.102, also tried new profiles of each of my browsers.
