Hi,
I have the same problem with the following error when I enter my current password and click the "Change Profile" button.
The following errors occurred when trying to save your profile:
The password you entered was not correct.
I am on OSX Mountain Lion and have tried Firefox (25.0.1), Chrome (31.0.1650.57) and Safari (6.1 (8537.71)), they all give the same error.
Thanks,
AB.
