Have you asked a friend? I can just confirm it is a browser issue because my firefox is set to store passwords and of course the password in that box is mine not something the program is making up. My test as stated I put in a test username test email and just filled in my password in the confirm box and the registration went fine meaning that password I see on my site is my password. On your site it is the 4 digit test password you posted in this thread. therefore it pretty much confirms there is no code error here with Photopost. No way to test anything else here that I see since I can confirm this on your site and my site. The passwords you are I are seeing are the ones we have used and entered when logging in so Mozilla is caching your logins. I do think you should be able to clear any saved passwords for sites in mozilla settings and you will see this disappear.
