[Plugin: Theme My Login] does not work with firefox

Hi,
When i try to login with firefox, I type my login name then password on typing the password all the page refresh. It’s like there is a link on typing the password that reset the page. It works with internet explorer.
I will add that when refreshed the login name and password fields are deleted…Then impossible to login.
Please help me as soon as possible, I tried to reinstall the extension but nothing was changed.

thanks a lot;
