This add-on will work as expected, but it will slow down the browser in situations not related to authentication. (e.g., multiple images view on Twitter)
This slowdown occurs not only in Firefox but in Chrome and Edge as well.
I've been using this add-on for many years but switched to Bitwarden when I found out that it causes slowdowns.

ouverture intempestive de fenêtres inutiles

Application intrusive avec une ergonomie catastrophique. Elle réclame tout le temps des réponses à des questions qui n'ont pas été posées. La demande de réponses est floue car ça demande en même temps de cliquer sur "Répondre" et de donner un mot de passe.
