I have tried several times to update my profile data. Each time I use the backspace key to correct a typo in a field, the program erases everything I've entered and I have to start over. It also takes me back to the last tab I viewed, like a browser "back" button.. I am about to delete my account due to the frustration this causes!
Why doesn't the backspace key function as expected, deleting only the last character typed and not causing a page back? I'd suggest you automatically save the entries in a temporary space, then later update the profile. Changing a tab within the profile update page also loses the entered info unless you click on the "save and continue" button, which is way down at the page bottom and not obvious.
