Fast saving of details.

Big annoyance with 1PW8 browser extension in Firefox. It suggests a new password for me, but the instant I click on it to accept the suggested password, it fills it, refills it in a confirmation field, throws up a Save dialog, but at the same time loads the next page where my new passwords have been accepted and the Save dialog is gone before I can click on the 'Save' button! Now I have created a new password of unimaginable complexity and it's not been saved.
Had to use a 'forgot password' link three times just now before I managed to hit Save before the dialog closed without saving.
This is dumb, and you simply have to fix it!
