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.

The program was working very well until a couple of weeks ago. Now it now won't start, I can't get Yubico to work anymore. There are missing screens.

NO FUNCIONA!!! NO PASA DE LA VENTANA DE ACEPTAR LOS PERMISOS, NO TIENE BOTON DE "NEXT" O ALGOPARECIDO PERO SI FUNCIONA EN CHROME

Einfach und Schnell

Worked OK for a while then stopped twice. Found a workarounds from others online however it's stopped working again with new Firefox update. Very frustrating.

it technically manages passwords, but everything about the extension user experience sucks.

It used to work but now it doesn't. I thought I would re-install it and that was worse, it doesn't even load the page where I accept permissions once I install it.

L'extension LastPass fonctionne très bien sur Edge et Chrome. Mais elle ne fonctionne plus sur Firefox.
Par contre cela fonctionne en mode administrateur sur Firefox.
Comment autoriser en autre mode ?
Aucune réponse en ligne apparemment.

I've been using this extension for many years and would previously have given it 5*; no more.

I have the premium as I use it on my mobile and laptop as well. until recently, there have been no problems and my privacy has been respected.

Now there is a pre-checked 'voluntary' data permission to hurdle when signing in on Firefox. This interferes with the operation of the extension by annoying you every time you use it, and makes the lie about not collecting personal information. This option should NEVER be pre-checked and placed next to the 'Decline' button as most would naturally decline additional data harvesting, particularly in my GDPR region. This pathetic attempt to harvest more info is starting to make me look elsewhere for a reliable, PRIVATE, password manager who doesn't try to use exasperation with constant badgering at start up.
