Using latest Firefox, I got this weird prompt on password change:

Not only that, it emailed me a new password for no reason. Never wanted to. Never requested it.
Do you have some kind of password-managing extension? Looks like something it might do, trying to be overly clever.
By latest Firefox which version do you mean, 1.5.0.4?
Yes, 1.5.0.4.
I am not using any sort of password/user extensions at all.
The web page (forum page) has no (client-side) scripting in it at all, so this must be some clever attempt by Firefox to store your modified password in its local cache of passwords.
I'm not sure why it emailed you the password, sounds strange.
Does an email change force a password change? If so, that was it.
An email address change forces a password change, in order to confirm that you can still be reached.
