Amazingly good.
Thank you so much for this jewel :D
EDIT: On 2025-August-24 I came to know about a vulnerability that could give all of my password to a website configured to exploit that vulnerability.
Therefore I disabled this and I think I will not use this addon again, although I will certainly keep using keepassxc which I think it's the best password manager that exists.

Fonctionne parfaitement pour moi sous W11/FF137.0.2, mais impossible de le mettre en oeuvre sous Plucky Puffin Kubuntu 25-04.
Je ne sais pas dans quel camp est la balle, mais ce serait bien que conjointement, la communauté Ubuntu, Mozzila et le développeur se donnent la main pour résoudre ce problème, qui semble connu...
Sans quoi, merci pour tout...

Works great, improves security with better passwords and basic protection against phishing. One of the two addons I have installed.

The shortcuts could be advertised more prominently: Alt+Shift+U triggers auto-fill.

It's handy, make my online life easier even filling those OTP inputs.
