Lastpass is my go to password manager

Twice now, I have accidentally clicked the grey "decline" button and the add-in UNINSTALLS itself without confirmation. This popups happens in every private window which I use to separate accounts saved in LastPass...

Immer wieder geht nix mehr , ach weg damit

Lässt sich nach Neuinstallation nicht mehr aktivieren

Desde hace unos días, supongo que desde que se actualizó a la última versión, dejó de funcionar, pide aceptar los permisos, pero no hay ningún botón de Next o similar.
En Chrome funciona.
Lo solucioné así: fui a versiones anteriores e instalé la anteúltima, de esa forma sí aparece el pedido de permisos en tamaño completo y te permite finalizar e instalar sin inconvenientes.
Pongo una sola estrella porque la solución debería haber venido del creador.

Not clear how it works!

Why should I have different PW to Log in into Last pass extension when I am using it on Firefox browser?

I have to use it because the company I work for uses it, but I'd rather not. It works, but it's horribly intrusive. Whenever I land on a page where I enter my credentials, it will offer to remember them for me: a popup appears in my browser, but it won't go away even when I ignore it. It stays there, until I explicitly close it. EXTREMELY annoying. Fortunately, I only need to use it once or twice per week, so I disable it as soon as I'm done with it, and use a much less intrusive password manager the rest of the time.

This is my pet peeve. I won't list the *many* other peeves I have. It's a horrible, horrible product that should never have been inflicted on computer users.
