Focus problem Puntuado con 5 de 5 estrellas

I'm confronted to a strange little problem :
If I find myself on a page for which I have log-in credentials and if at the same time I have not logged in to Master Password and disabled notification to do so, then I lose focus of the Web page just as if a hidden notification pop-up was getting that focus. Now at this point I ignore if it is related to my system or not. A bit bothering, moreover if I have another user on the computer and wish that sites for which I have a login be not revealed ...
Has anyone else experienced this issue ?

"Pro" as professional Puntuado con 5 de 5 estrellas

Having abandoned 'LastPass' and now using Firefox's built-in password manager (which by the way is well done), 'Master Password+' appears to be the perfect complement, easy as logic is, "pro" in its handling of every detail. I also appreciate the option of refusing access to the browser itself without typing the master password at start. Very nice achievement.
