Firefox seems a bit whimsical regarding add-ons. I have one I have used with Foxfire, but now Foxfire won't add it.
Firefox isn't contesting the authenticity of the add-on. I would accept their advice in that matter. This one seems legit and Foxfire is being adamant. Insufficient explanation. I am not pleased.

Similar great as SecureSafe regarding password function. But Proton Pass offers the 2FA Autenticator integrated in the password app. This is great!

no real complaints, great that it ties in with the rest of the Proton suite

Incredibly easy to create email aliases. No 2 online accounts have the same email for me and that makes managing compromised accounts VERY easy, and also adds to my online privacy. That kind of sounds like an ad, so I'll throw a small negative in there too - it sometimes has problems detecting login boxes on some sites and the passkey thing only works 90% of the time.

I am a paid customer. Been using for over a year now. The team at Proton does a great job at adding new features. Though some sites are picky about the built-in passkey implementation.

Bonne extension qui complète bien l'application. J'apprecie particulierement la création très facile d'alias mail lors de l'enregistrement d'un nnouvel identifiant.

Il y a encore des progrès à faire sur la reconnaissance des champs sur beaucoup de site où ProtonPass ne marche pas. 1password ou Dashlane reste plus efficace sur point.

Mais Proton nous offre regulièrement de nouvelles fonctionnalitées, l'équipe est dynamique et je ne doute pas l'appli va encore progresser.

Absolutely fantastic and getting updated constantly. The whole company is honestly fantastic.
